works fine here @starssurfer. a quick copy/ paste;
Autoptimize does not have its proper cache purging mechanism, as this could remove optimized CSS/JS which is still referred to in other caches, which would break your site. Moreover a fast growing cache is an indication of other problems you should avoid.
Instead you can keep the cache size at an acceptable level by either:
disactivating the “aggregate inline JS” and/ or “aggregate inline CSS” options
excluding JS-variables (or sometimes CSS-selectors) that change on a per page (or per pageload) basis. You can read how you can do that in this blogpost.
Despite above objections, there are 3rd party solutions to automatically purge the AO cache, e.g. using this code or this plugin, but for reasons above these are to be used only if you really know what you’re doing.
