 * Hi bilimokur,
 * My mistake. css_async.js error should hit by your rewrite rule:
    `RewriteRule.(
   css|js|jpg|jpeg|png|gif|ico|swf|bmp)$ - [nocase,redirect=404,last]`
 * Method 1:
    Try exclude all ‘/min/’ file Method 2: Remove the rewrite rules

   |swf|bmp)$ – [nocase,redirect=404,last] RewriteEngine On RewriteCond %{REQUEST_FILENAME}!-
   f RewriteRule .(css|js|jpg|jpeg|png|gif|ico|swf|bmp)$ – [nocase,redirect=404,
   last] ` You can check this [https://www.shoutmeloud.com/how-to-edit-your-wordpress-htaccess-file.html](https://www.shoutmeloud.com/how-to-edit-your-wordpress-htaccess-file.html)
