FlyingPress Not Working Right? Fixing Cache, Layout Breaks, and Slow Pages
FlyingPress usually works quietly in the background. You install it, turn it on, and your WordPress site gets faster without much drama. But every so often something looks wrong after activation: a page that refuses to update, a layout that suddenly breaks, images that appear late, or a shop cart that behaves strangely. Before you panic and deactivate everything, know this — almost all FlyingPress problems have a boring, fixable cause, usually a stale cache or one optimization setting that conflicts with your theme or another plugin. This guide walks through the most common ones, with practical fixes you can apply in minutes.

Before You Touch Anything: Back Up and Use Staging
This is the rule that saves you from every other mistake in this article. Before changing optimization settings on a live site, take a full backup — files and database — and, if your host offers it, test risky changes on a staging copy first. Optimization settings change how your pages are built, so a bad combination can briefly break the visible layout even though nothing is permanently damaged. With a backup and a staging site, you can experiment freely and restore in minutes if a setting misbehaves. On a live store, never test during a busy sales period; pick a quiet hour instead.
If you do not yet have FlyingPress running, the FlyingPress plugin page explains the activation model: the WP Theme Bazar team activates the original license directly on your site, and the private license key is never shared. That matters for troubleshooting too, because it means you should not go hunting for a key to re-enter — if activation itself is the problem, contact the team rather than trying to force it.
Problem 1: "I Edited a Page but Nothing Changed"
This is the single most common FlyingPress complaint, and it is almost always stale cache rather than a real error. When page caching is active, visitors — and sometimes you — are served the stored copy of a page, not the freshly edited one.
Start with the simplest fix: purge the cache. FlyingPress provides a purge option; clear the cache for the edited page first, and if that does not work, purge everything. Then reload the page in a private or incognito browser window, which skips your browser's own stored copy. If the change still does not appear, clear your browser cache as well, or test from a different device.
If the problem keeps coming back on one specific page — a homepage that updates often, for example — check whether that page is one you should exclude from caching, or whether another layer is caching it too, such as your host's server cache or a CDN. Two caches stacked on top of each other can make purging one of them look like it did nothing. Also check smart cache preloading settings: preloading rebuilds cached pages in the background, which is normally a good thing, but if it runs before your edit is fully saved, it can briefly re-cache the old version. Purge once more after saving and the fresh version should stick.
Problem 2: Layout Breaks or Styles Look Wrong After Turning Optimization On
A broken layout after enabling CSS or JavaScript optimization is alarming, but it is usually one setting disagreeing with your theme. The classic symptom is a page that loads unstyled, with content stacked vertically, or with menus and sliders that stop working.
To find the culprit, turn optimization features off one at a time and test after each change. Start with JavaScript delay and defer settings, because scripts your theme expects to run immediately — sliders, menus, forms — are the most common breakage. If the layout recovers, you have found it. Then use an exclusion option for that specific script or stylesheet, so you keep the speed gains everywhere else while letting the one troublesome file load normally.
The same logic applies to CSS optimization. Removing unused CSS is powerful, but a theme or page builder can load styles in ways the optimizer does not expect, and a class that looks unused on one page may be essential on another. If a specific template — a landing page, a checkout page, a builder page — breaks while the rest of the site is fine, exclude that page or that stylesheet and move on. Do not try to fix a layout break by editing theme files; the problem is almost certainly a setting, not your theme.
Problem 3: Images Load Late or the Largest Image Hurts Your Score
Lazy loading is one of FlyingPress's best features, but it can backfire on the hero or featured image at the top of the page. If the largest contentful paint element — usually the big image a visitor sees first — is lazy-loaded, the browser delays exactly the image it should show immediately, and your Core Web Vitals score suffers along with the perceived speed.
The fix is to exclude above-the-fold images from lazy loading. Your hero image, logo, and any image visible without scrolling should load normally, while images further down the page can stay lazy-loaded. FlyingPress's image optimization, including AVIF and WebP conversion, is a separate feature from lazy loading, so you can keep the smaller file formats while fixing the loading order.
Also check for a related trap: lazy loading inside sliders and carousels. Images in the second or third slide are often treated as below the fold even though the slider itself is at the top, and the result is a blank slide or a visible pop-in. Excluding slider images from lazy loading usually solves it in one step.
Problem 4: Cart, Checkout, or Account Pages Misbehave on a WooCommerce Store
WooCommerce and aggressive caching are natural enemies, which is why FlyingPress builds in WooCommerce support and excludes the cart, checkout, and my-account pages from caching. If your store still shows a stale cart total, a checkout that does not update, or a customer seeing another session's data, something has overridden that protection.
First, confirm that no other caching layer is caching those pages — a host cache, a CDN page rule, or a second caching plugin running alongside FlyingPress. Two optimization plugins active at once is one of the most reliable ways to create strange behaviour, so deactivate any other cache or minify plugin before blaming FlyingPress. Second, check whether you have added custom pages that behave like cart or account pages, such as a custom checkout or a membership dashboard; those may need to be excluded from caching manually, since the built-in exclusion only covers the standard WooCommerce pages.
If the problem is a payment gateway script failing after JavaScript optimization, exclude the gateway's scripts from delay and deferral. Payment scripts need to run exactly when the gateway expects them to, and delaying them to save a fraction of a second is never worth a failed transaction.
Problem 5: The Site Feels Slower, Not Faster
It sounds backwards, but a site can feel slower right after optimization is switched on. The usual cause is that the cache is still warming up: the first visit to each page builds the cache, and until preloading has covered your important pages, some visitors still hit uncached pages. Give smart cache preloading time to finish, then test again. Clearing the entire cache repeatedly during testing makes this worse, because every purge sends the site back to uncached performance until pages are rebuilt.
Another cause is image optimization running on a huge backlog. Converting a large media library takes time and server resources, so let the queue finish during a quiet period before judging the result. If slowness persists, try database optimization: a bloated database full of old revisions and transients can slow background work, and a careful cleanup — after a backup — often helps more than another caching toggle.
Problem 6: Plugin or Theme Conflicts
When a form stops submitting, a popup stops appearing, or a builder stops saving, and the timing lines up with enabling FlyingPress, a conflict is likely. The fastest diagnostic is to temporarily disable FlyingPress and test: if the feature works again, the conflict is real. Then re-enable FlyingPress and disable optimization features one by one, as described above, until the feature returns. That tells you exactly which setting to exclude or adjust, rather than forcing you to choose between speed and functionality.
Keep a short note of every exclusion you make and why — it turns a future re-diagnosis into a five-minute fix.
A Quick Diagnostic Checklist
When something looks wrong, work through this list in order rather than changing five settings at once: purge the cache and test privately; check for another cache, CDN, or optimization plugin; disable JavaScript delay and deferral; disable CSS optimization; disable lazy loading; check WooCommerce exclusions for store problems. The step where the problem disappears points at the setting to adjust.
For reference, the FlyingPress plugin covers page caching, smart cache preloading, image optimization with AVIF and WebP, CSS and JavaScript optimization, lazy loading, database optimization, resource prioritization, and Core Web Vitals tracking. Knowing that full list helps during troubleshooting, because it reminds you which features exist to be toggled — most problems are one of these features meeting one unusual page, not a broken plugin.
When to Ask for Help Instead of Guessing
Some situations deserve a second pair of eyes rather than more toggling. If the site shows a white screen or a server error after a settings change, restore your backup or revert the last change before anything else. If a WooCommerce checkout is failing on a live store, disable optimization on the checkout flow immediately and sort out exclusions afterwards — lost orders cost more than a slightly slower page. And if activation itself is the issue, remember the seller-assisted model: the WP Theme Bazar team activates the original license directly on your site, so reaching out to them is the correct route rather than attempting to reinstall or re-enter a key you do not have.
Most FlyingPress problems are solved by the basics: purge the cache, test privately, disable one feature at a time, exclude the single troublesome file or page, and keep a backup before every experiment.

Frequently Asked Questions
Why does my edited page not update after I save it?
Usually the old cached copy is still being served. Purge the FlyingPress cache, then test in a private browser window to rule out your browser's own cache.
What should I do first when the layout breaks?
Disable JavaScript delay and deferral first, then CSS optimization, testing after each change. When the layout recovers, exclude the specific script or stylesheet that caused it instead of leaving the whole feature off.
Should the hero image be lazy-loaded?
No. Images visible without scrolling, especially the largest image on the page, should be excluded from lazy loading so they appear immediately.
Why is my WooCommerce cart showing wrong totals?
Check for a second caching layer or plugin caching the cart, checkout, or my-account pages. FlyingPress excludes those standard pages by default, but another cache can override that protection.
Is it safe to change settings on a live site?
Take a full backup first and test risky changes on staging when possible. Never experiment on a live store during a busy period.
Can I use FlyingPress alongside another caching plugin?
No, you should not run two caching or optimization plugins at once. Deactivate the other one before troubleshooting FlyingPress.
