 * Hi There. Thank you in advance.
 * I have been using Fast Velocity Minify for a couple of years with no problem.
   Recently, while logged in I continued to get a blank screen and error saying 
   something to the effect of “fatal error: …. memory exhausted… fast velocity minify“.
   Because of this I disabled your plugin to attempt to solve it, but then it caused
   problems with my theme as a whole (perhaps code now needs your plugin to run 
   correctly at all).
 * I have since solved the memory allocation problem, however now my shortcodes 
   for my sliders on all pages (mobile and tablet view only) are no longer functioning.
   The images are present and the code still on the page, but slider not working
   and images are stacked and not sliding.
 * I have tried one-by-one to deactivate CSS, HTML, and JS minify to solve it with
   no resolve. I have also turned off all caching plugins with no resolve either(
   I have since reactivated).
 * Please look over my site and let me know if you have a fix/immediate resolution
   for this. I have tried everything I know to fix.
 * Thank you in advance.

 * Hi there,
 * Sliders not working is a common issue with merging and minifying, because scripts
   conflict when merged together.
 * I also want to make clear that this plugin doesn’t do any modification on your
   theme or plugins. It grabs the enqueued files (only), dequeues them, merge them
   together into another file and saves it on the uploads folder. Deleting the plugin
   or deactivating it, will simply stop doing that and the website will work as 
   usual.
 * In your case, you say that the theme got used to using my plugin…
 * No, what happens is:
 * a) Your server has some sort of cache that you are not able to delete, even though
   you are purging the cache yourself. This has happened before, and it’s something
   server related on a few hosting providers.
 * The same is true for the memory allocation problem.
    Perhaps the server is overloaded
   and when you run some intensive scripts it crashes (try to disable the html minification).
   Or perhaps, they updated something and it broke some functionality, or perhaps
   you updated other plugins and one of them is causing the issue under certain 
   queries.
 * Solution for cheap hosting? Well, get a proper server from cloudways.com The 
   cheapest plan is $7 or get it directly from digitalocean for $5.
 * b) When you customize your site and then keep doing updates on your theme, wordpress
   and your plugins, it’s definitely going to break something someday.
    If you have
   customized your theme code, updating it will overwrite any changes. If you’ve
   done it to a plugin, it’s the same thing. If you update wordpress core and it
   ships out with a new jQuery version, some plugins may stop working as old commands
   get removed from newer jQuery libraries, even though it it used to work before.
 * Now, because FVM caches CSS and JS code into new static files at a given date
   under the uploads directory, you may not immediately see things breaking when
   you update, because you are effectively seeing the FVM version, that merged files
   on a given date in the past… possibly before the update.
 * If you read our faqs [https://wordpress.org/plugins/fast-velocity-minify/faq/](https://wordpress.org/plugins/fast-velocity-minify/faq/)
   
   It says you should purge the cache on the plugin settings, so that it picks up
   the new updated js and css files. If you don’t do that, you may be seeing older
   versions.
 * In that case, deleting the plugin will show you the real files from your plugins
   and themes without anything else, therefore if one of the updates have broken
   somethings, you will see it.
 * Disabling FVM usually deletes the cached file and tries to restart the whole 
   process again, therefore, reenabling it again, will not work as you expect, because
   it fetches the newer JS and css files directly from your site and generates a
   new cache file.
 * In other words, if it’s broken without FVM, there’s no way FVM can fix it once
   you purge the cache. It may look like it’s working before you purge the FVM cache,
   but it’s only temporarily.
 * My advice to you…
 * Disable FVM and any merging / minifying plugins or options in the theme or any
   plugins.
    That will give you the default site without any optimizations.
 * If it doesn’t work, there was a theme, plugin or core update somewhere that broke
   something. Nothing you can do, other than redoing your code changes or restore
   the files from an older backup you may have (no need the database, the files 
   only will do).
 * If you’re lucky to have a backup, update the plugins one by one and find out 
   which one breaks things. Make sure to purge your browser cache completely, as
   well as any cdn or cloudflare, and server cache.
 * If you get the memory error or other cache issues, trust me on this and get a
   cheap vps plan on cloudways. Even the cheapest vps plan will be miles ahead of
   a normal hosting account.
 * Nothing I can do, as your issue is not related to FVM in any way.
    Your site 
   needs to be able to work fine without it, before you can use it. Working before
   and for may years, is only relevant if you never done any updates… the case is,
   if it broke you must have updating something that caused the issue.

 * The issue with the memory allocation has been ongoing and I see many other people
   relating it to your plugin. It is an easy thing to say that it has nothing to
   do with it, but it’s a constant between other users so there is definitely an
   incompatibility and something within the plugin that should be modified. I see
   you attempted to prior but even with those updates it did not solve it. I solved
   in a roundabout way through other means.
 * Further, the slider issue only began occurring as soon as I deactivated your 
   plugin. Prior, there were no issues. Furthermore, there is zero wrong with my
   hosting as this has been our hosting for several years with no problems whatsoever,
   using our caching plugins, this theme, and Fast Velocity Minify.
 * While I appreciate you responding, I do not find a resolution in this answer.
   It is easy to say to everyone who comes to you that it is not related to fast
   velocity minify and have them be on their way.
 * Currently, if I turn off your plugin my site loses all its CSS. I turn it back
   on, everything goes back into place but slider function not working. I am basically
   stuck with your Plugin and you are telling me it has nothing to do with the problem.
   That’s a very easy copout but extremely unhelpful.
 * If you care to look for reference, I have since turned off your plugin and will
   leave it that way for an hour or so so you can see how the site is malfunctioning.
   I will turn it back on then try to find a solution on my own if you are unwilling
   to look into this issue in depth to solve.

 * I’m not sure if you read my previous reply, but you either didn’t understand 
   what I said, or completely bypassed the part that says, that my plugin doesn’t
   touch any file on your site.
 * In fact, every single plugin on the official repositories is verified by the 
   wordpress team to ensure that it doesn’t have destructive behaviour.
 * Furthermore, all plugins existing here, are exactly just that (plugins). That
   means, disabling any plugin, will make wordpress not using it at all.
 * To be even clearer, disabling FVM will simply return wordpress to its original
   state… but dont misunderstand my words here. By returning to the original state,
   I mean that FVM will simply not be in use anymore. There is nothing to be reverted,
   only a layer of functionality that was added on top, that can be enabled or disabled
   any time.
 * If you don’t understand how wordpress plugins work, please google about it. A
   plugin doesn’t modify your site files themes or other plugins.
 * You talked about a recurrent issue with my plugin showing memory issues… Well,
   I read every single support request and don’t see that.
    Can you perhaps point
   me to some of those, where people didn’t actually admit it was server related?
 * A server runs out of memory due to multiple situations. It can happen to any 
   plugin or like you said, with FVM alone on your site.
 * That doesn’t mean it happens to the other 20,000+ sites using FVM, because people
   use diferent servers, themes, and other plugins.
 * A memory issue is server related.
    A site or plugin tries to do something normal,
   and the server is so slow or is so restricted, that it cannot process the request,
   thus showing that message. It may not happen all the time, because the server
   load is not constant.
 * The key here, is to check wheter it happens once in a while or always, and if
   you google that error, its very easy to find how cheap / old / low quality hosting,
   place memory limits on even a default install of wordpress.
 * Can you post a screenshot, of the server settings tab on FVM? That page exists
   for situations like these, where we need to see what are the server capabilities.
 * All that being said, I have so many years of experience troubleshooting wordpress
   sites, that “I Know” (definetely), that if the site doesn’t work when you disable
   a plugin such as FVM (or a cache plugin), that its something server cache related.
 * There is no way around it other than to ask the hosting to purge the file structure
   caching.
    If you read some support requests, you can read exactly about this.
 * Some hosting providers use remote slow storage… so they cache your files in such
   a way, that even if you purge your cache and physically delete all your wordpress
   files… the server still has them in the memory.
 * I’m not going to discuss further about your hosting, especially when you think
   you know better and immediatly discard that possibility, even though any developer
   will tell you otherwise.
 * Also to be crystal clear about this, please read the license for GPL plugins,
   for any wordpress plugin here.
 * Its your sole responsability to keep backups, or if you break your site while
   using any plugin from the repositories of wordpress.org
    Neither I, WordPress
   or any theme / plugin author have the “responsability” to fix your site when 
   you install anything from here.
 * Don’t get me wrong here… I am just making things clear, so you understand that
   I will help you, but I actually have no “obligation” to do so.
 * Sure, I care about my product and I don’t want your site to break because of 
   it.
 * Unfortunately, I know its a server cache issue (or your browser too) because 
   activating FVM makes it work again.
 * If you purge the cache on FVM status page, it will still work… however, I am 
   99% sure it will stop working when someone restarts the server and the cache 
   is gone.
 * Whichever reason, I can help you fixing it, however You need to contact me via
   fastvelocity.com contact form, since I am not allowed here to ask for other information
   that can help me solve your issue.
