This is a terrible side effect of using Divi and another reason I’ll never use it again for client websites. 1. First, disable “Static CSS File Generation under Divi Options > Builder > Advanced. 2. Next, delete the ET Cache Folder either in File Manager or via FTP. 3. Lastly, edit your wp-config.php file by adding this line: define( ‘ET_BUILDER_CACHE_MODULES’, false );
If you can’t tell I’m not a fan of Divi at all. Hopefully this helps.
