 * After enabling CSS optimization, my site layout breaks. How do I identify which
   CSS files are causing the issue?

 * Hi [@dinahens](https://wordpress.org/support/users/dinahens/),
 * I’m afraid, without seeing the site live it isn’t clear what exact issue you 
   are noticing. You can start by checking the browser console for errors to rule
   out what might be causing the layouts to break.
 * Please check this for more info:

 * If the above doesn’t help much then please do share a screenshot of the exact
   issue you notice, and if possible share the site URL where you notice the issue
   so that we can take a closer look.
 * Looking forward to your response.
 * Kind Regards,
