 * Hey,
 * I love the simplicity of this plugin but i’m fairly new to all this stuff and
   when I tick on the optimize CSS code it breaks the website and doesn’t load in
   any CSS.
 * My problem is I have no idea where to start to look or diagnose the break let
   alone fix it.
 * Our site is printflex.com.au.
 * Thanks,
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcss-wont-load-when-optimize-css-code-is-selected%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hey [@printflex](https://wordpress.org/support/users/printflex/);
    If you have
   a non-production site I’d be happy to have a look at what’s going wrong there.
   Alternatively (well, somewhat at least); you could re-enable autoptimize briefly
   on production and then run a test on [https://webpagetest.org](https://webpagetest.org)
   and provide me with the resulting URL with the test result.
 * Kind regards,
    frank

 * Hey Frank,
 * Thanks for the reply, this is the results I achieved from running that test.

 * The webpagetest.org result didn’t really help, but you still have (had) AO active
   so I was able to troubleshoot. So can you try adding `uni-woo-custom-product-
   options/assets/css` to the comma-separated CSS optimization exclusion-list?

 * That works perfectly,
 * Thanks for your help. A 5 star rating is coming your way.
