   WordPress dashboard:

   a status of 404 () (wp-optimize-global-3-3-2.min.css.map, line 0)[Error] Failed

 * Could you please let me know which versions of the WP-Optimize plugins you are
   currently using? If they are not the latest versions, please update them to the
   latest version and check if the issue persists.
 * If you are already using the latest versions, could you share the Site Health
   information from your WordPress dashboard? This will help us diagnose the issue
   further.
 * To get the Site Health info:
    1. Go to your WordPress dashboard.
    2. Navigate to **Tools** > **Site Health**.
    3. Click on the **Info** tab.
    4. Click on **Copy site info to clipboard** and paste it in [pastecode](https://pastecode.io/)
       and share the URL here.
 * This will help us better understand your setup and provide more accurate assistance.

 * Hi [@wpmansour](https://wordpress.org/support/users/wpmansour/),
   I’m using the
   3.3.2 versions because newer updates are broken. I am going to test the upcoming
   3.4.2 update and I will let you know if the issue persists.
