 * Hello,
 * I’ve recently started to have some critical issues prpbably related to my Autoptimize
   settings.
 * For example, my server went down everytime I activate a plugin. Like onesignaL
   or topbar. For Onesignal I’ve solved excluding their JS from autoptimize. but
   then I’ve tried another plugin like mystickymenu and server started to slow downw
   losing traffic. I don’t know what to do anymore. these are the kind of errors
   I encounter on chrome dev tool (console tab)
 * Failed to load resource: the server responded with a status of 404 ()
 * OR
 * GET [https://www.smartdomotica.it/wp-content/cache/autoptimize/js/autoptimize_0895fec71d7c502d7b61de90e5f879f2.js](https://www.smartdomotica.it/wp-content/cache/autoptimize/js/autoptimize_0895fec71d7c502d7b61de90e5f879f2.js)
   net::ERR_ABORTED 404
 * Could you please advise? Right now the traffic is halved and server is slow. 
   Also, I’m using autoopmtize combined with WP Super Cache (recommended by the 
   author of my theme rehub). thanks

 * 404’s (not found) typically happens when Autoptimize’s cache is cleared and the
   page cache is not. clearing all page caches _should_ fix things. but -at least
   on the homepage- the files seems to load OK? are there specific pages that are
   broken?

 * thank you. When I activate a plugin and I experience the server going down the
   images on homepage in incognito mode do not load – apart from these links and
   stuff seem ok apart from the decrease of real time traffic, of course

 * No idea what is happening there I’m afraid. what you could do is experiment with
   Autoptimize settings to confirm which might be causing issues?
 * Start by just disabling CSS or JS or HTML or Image optimization (incl. lazyload)
   to see which one does (not) work?
 * hope this helps,
