 * hey lazospap3;
    as per the troubleshooting guidelines in [the FAQ](https://wordpress.org/plugins/autoptimize/#faq)
   best approach is to enable only CSS or only JS optimization to see which one 
   is causing the server error. based on that we can see what the next steps should
   be.
 * hope this helps,
    frank

 * When i have enabled only the CSS optimization everything workings but i have 
   some off CSS rules abolition example : my view button from my product hover is
   not on center as it was.
    But when i enable the JS optimization the white page
   appears in my home page. So and the CSS abolition some of my CSS rules that i
   have created and on the other hand the JS optimization white page my home page.

 * re. the smaller CSS issue; try unticking the “also aggregate inline CSS”-option.
   alternatively you might have to exclude some CSS from optimization.
 * re. the bigger JS issue; can you check your php errorlog for relevant PHP-errors?
   alternatively you can try excluding your JS-files one at a time to find the culprit.

 * well, you might i that case have to exclude some (mobile-specific) CSS from optimization?
 * > How can i do that if you can provide me some steps.
 * Regarding your PHP-errorlog; that depends on if/ where your hoster has the php-
   errors logged, better check with them?
 * Regarding excluding JS; have a look a the AO FAQ (linked above) for info on how
   to exclude.
 * But I think the reason for the white screen is that you also have hummingbird
   do JS minification. having 2 (or more) plugins doing the same thing can lead 
   to unforeseen things (like white screens) I’m afraid. So if you want to use Autoptimize
   disable Hummingbird for CSS & JS minification and things will probably work a
   lot better 😉

 * Yeah it was that reason the plugin Hummingbird was making the problem thank you
   for your tip!
 * It worked in the mobile too the CSS in mobile is fixed.
