144	- You must disable any features on your theme and other plugins, that perform minification of css, html and js.
145	- You cannot also have other optimization plugins, because you are forcing wordpress to do double work.
146	- I recommend W3 Total Cache (with css, js and html minifcation disabled) + Fast Velocity Minify, for minification of CSS and JS files.

152	- Likewise, you can keep CSS processing and disable JS processing to find out if the problem is on JS processing.
153	- If you determine it's a CSS issue, check the log file on the status page for possible css file urls that should not be there (such as Internet Explorer only files) and add them to the ignore list.
154	- Also kindly report those files on the support forum so they can be blacklisted for future releases.
155	- Sometimes there are JS files than conflict with each other when merged so they may need to be excluded too.

160	- On Google Chrome you can look at the console by pressing CTRL + SHIFT + J on your keyboard and refreshing the page. If there are errors you need to track down which JS file is causing trouble and add it to the ignore list.
161	- If you have no idea which files to add, I recommend checking the log file on the status page, adding them all to the ignore list and then one by one trying to delete each url until you find the one causing trouble.
162	- Also beware of any cache plugin in use (and cloudflare) when testing, because that cache needs to be off or purged when configuring things around.

169

175	- There are also files meant to be loaded for IE users only, mobile users, desktop users, printers, so the enqueing of all the files needs to follow the official method of enqueing data and files.
176
177	- This can also cause layout issues because some files that should be for IE only can be merged together with other users, thus overwriting the usual layout (please check if any of those got merged together and add it to the ignore list). Also, to avoid some of these, we have implemented an IE only blacklist of "known" file names that are "always" added to the ignore list behind the scenes.

191	-
192	- While this is rare, it can happen if you have some sort of cache enabled on your site or server. A cache means that the site or server makes a static copy of your page and serves it for a while (until it's deleted or expires) instead of loading wordpress directly to the users. Some hosting providers such as Godaddy (and their derivates) enforce their own cache plugin to be installed and creates a new menu which allows you to purge the cache.
193
194	- If ~~you~~ ~~don~~'t ~~see~~ any ~~option~~ ~~anywhere~~ to ~~clear~~ your ~~cache,~~ ~~you~~ ~~can~~ ~~contact~~ ~~your~~ ~~hosting~~ ~~provider~~ or ~~developer~~ to ~~clear~~ the ~~cache~~ ~~for~~ ~~you~~ or ~~ask~~ ~~them~~ ~~how~~ you ~~can~~ do it in the ~~future~~.

213	- ~~This means, we cannot easily capture that css code and therefore it's left out of all the merging by Fast Velocity Minify.~~
214	- ~~You~~ ~~may~~ ~~have~~ all ~~else~~ ~~merged~~ ~~and~~ ~~minified~~ ~~correctly~~, ~~however~~ if ~~that~~ ~~generated~~ ~~visual~~ ~~composer~~ ~~css~~ ~~code~~ is ~~important,~~ ~~those~~ ~~styles~~ ~~might~~ be ~~overwritten~~ ~~by the merged file~~, or ~~that~~ ~~code can also overwrite~~ the ~~rules~~ ~~inside the css generated file~~.

219	= How should I use the "Preload Images" and what is it for? =
220
221	- Certain themes and plugins, either load large images or sliders on the homepage. Most of them will also load "above the fold" causing the "Prioritize visible content" or the "Eliminate render-blocking JavaScript and CSS in above-the-fold content" message on pagespeed insights ~~(see the previous faq question above)~~.
222
223	- ~~How~~ you can use the "Preload Images" is ~~by adding~~ the ~~url of the~~ first relevant images that load above the fold, such as the ~~first~~ ~~background~~ ~~image (and~~ the first image ~~only)~~ of ~~the~~ slider. ~~Any~~ ~~big~~ or ~~large~~ ~~enough image that~~ is ~~above~~ ~~the~~ ~~fold should be added here, however note~~ that ~~the~~ ~~images~~ ~~you~~ ~~add~~ ~~here "must" actually exist on the page~~, ~~else it will trigger a warning on the browser console such as "The resource [...] was preloaded using link preload but~~ not ~~used~~ ~~within a few seconds from~~ the ~~window's load event~~. ~~Please make sure it wasn't preloaded for nothing." which is not good practice.~~
224
225	- Don't put too many ~~resources~~ here as those are downloaded in high priority and it will slow down the ~~page load on mobile or slower connections (because the browser won't process the~~ rest ~~until it finishes downloading all~~ of ~~those~~ ~~big~~ ~~"preload" images)~~.

89	+ Different pages may need different JS and CSS files per page, post, category, tag, homepage or even custom post types, but if the requirements never change and you always load the exact same files on every page, you won't see as many files.

143	+ = After installing, why are some images and sliders not working? =
144
145	+ a) You cannot do double minification as it will break things, so make sure you have disabled any features on your theme or other plugins, that perform minification of css, html and js files.




146
147	+ b) Are you trying to use the defer JS or CSS options, without understanding exactly how it works? Be advised that most themes do not work properly with those options on.
148
149	+ c) The plugin relies on PHP Minify to minify javascript and css files, however it's not a perfect library and there are plugins that are already minified and do not output a min.js or min.css name and end up being minified again. Try to disable minification on JS and CSS files and purge the cache.




150
151	+ d) Sometimes a plugin conflicts with another when merged. Try to disable CSS processing first and see if it works. Try to disable JS processing second and see if it works. Try to disable HTML minification last and see if it works. If one of those work, you know there's a conflict.
152
153	+ e) If you have a conflict, try to add each CSS and each JS to the ignore list, one by one until you find the one that causes the conflict. If you have no idea which files to add, check the log file on the status page for a list of files.

162
163	+ Because "printing CSS and JS tags on the header and footer is evil" (seriously), we cannot capture those files and merge them together.
164
165	+ There are also specific ways to enqueue files meant to be loaded for IE users only, mobile users, desktop users, printers, etc, else those may be merged together and break things. There is a blacklist and default ignore list on the PRO tab because of this.

170
171	+ This is an advanced option for highly skilled developers. Do not try to fiddle with these settings if you are not one, as it will almost certainly break your site layout and functionality.
172
173	+ Loading CSS async only works properly and consistently, when you have one single CSS file being generated and your critical path is generic enough to be common on all pages.

182
183	+ = Why is it that even though I have disabled or deleted the plugin, the design is still broken? =
184
185	+ Some "cheap" or so called "optimized" hosting providers, implement a misconfigured and agressive cache on their servers, and then are also "smart" enough to ignore your multiple cache purge requests if those are too frequent.
186
187	+ Some providers use a "deploy system", where you upload / replace / delete the files via sftp, but those are not reflected on the live site immediatly. This means that in some cases, you can delete your whole wordpress instalation via sftp, and the site still works perfectly fine even after purging the cache.
188	+
189	+ You may have deleted the physical files from the disk, but that's either just some random storage they gave you and that they sync to the main server every few hours, or it may be the actual live server but with a file cache layer on top of it (so the old code keeps running even though you have deleted the files).
190
191	+ The only solution is to contact your hosting company and ask them why you have deleted the plugin and purged your cache, but the live site doesn't reflect the changes.
192
193	+ Providers well known to have this issue are hostgator and iPage (please report others if you find them).

If you encounter such issue of your page editor not working on the frontend, kindly enable the "Fix Page Editors" and purge your caches.
