 * in that case make sure to clear any page cache you or your host might have, that
   _should_ fix it.
 * additionally make sure the “Enable 404 fallbacks?” option is active and test 
   if it works. if it does not work out of the box some changes might be needed 
   on a webserver configuration level.
 * hope this helps,
    frank

 * Hi,
 * I just wanted to follow up and let you know that there are still 404 errors, 
   and when I try to delete the autoptimeze cache, the wp-content/cache/autoptimize
   does not empty.
 * The wp super cache does empty the folder, so I assume the CSS and js files are
   the cache that stays after that.

 * but clearing the AO cache will not fix 404 errors (on the contrary), it is the
   page cache (wp super cache and any other page caching solutions you or your host
   might have) that should fix the 404’s actually.
