    While using WP-Optimize 4.4.0, I ran into the following two errors. Is there a way to fix these?

    1.  Error: Unable to Check GZIP Compression. We encountered a problem while checking if GZIP compression is enabled.

    The server responded with a 403 403 Forbidden error whilst trying to open the URL: https://simplygreatrecipes.com/wp-content/themes/ashe-pro-premium/style.css. Please contact your website administrator to resolve this. Once the issue is addressed, try again.

    2. Error: Unable to Check browser cache. We encountered a problem while checking if browser cache is enabled.

    The server responded with a 403 403 Forbidden error whilst trying to open the URL: https://simplygreatrecipes.com/wp-content/themes/ashe-pro-premium/style.css. Please contact your website administrator to resolve this. Once the issue is addressed, try again.

    Hi,

     

    Thank you for the details.

    Those two WP-Optimize errors are **not related to the Ashe Pro theme**. The key point is the **403 Forbidden** response when WP-Optimize tries to fetch this file:

    https://simplygreatrecipes.com/wp-content/themes/ashe-pro-premium/style.css

    A **403** is a server/security permission block, typically caused by one of the following:

    * Hosting/firewall rules (WAF)

    * A security plugin (Wordfence, iThemes, Sucuri, etc.)

    * Server rules in .htaccess / Nginx config

    * Hotlink protection or bot protection

    * Cloudflare / CDN rules

    Because WP-Optimize cannot access that file, it fails to verify GZIP and browser cache.

    What to do next:

    1. Check your hosting/security layer for rules blocking automated requests to /wp-content/ or specifically style.css.

    2. Temporarily disable any security plugin and test again.

    3. Contact your hosting provider and ask them to whitelist WP-Optimize’s check requests or remove the rule generating the 403.

    4. If needed, contact **WP-Optimize support**, since it is their tool running the checks and they can tell you exactly what user-agent/IP/request pattern is being blocked.

    From the theme side, there is nothing to change — the theme is simply a file being requested, and your server is refusing access.

     

    Kind Regards
