    Hi Dick

    I hope you’re well today and thank you for your question!

    I checked the site but it seems there’s some additional issue there that we’d need to address first. When I’m trying to access any of Defender pages in back-end I only see blank pages and a lot of 500 errors in browser console.

    This means that there’s either some conflict or some resource issue. The problem that you have described would most likely be related to either “Prevent PHP Execution” or “Information Disclosure” tweaks or to one of the “header security” tweaks but that would have to be tested and can’t be without access to Defender configuration.

    That said, it would be best to start with checking WP debugging output. Please follow these steps:

    – access the site WP installation using FTP (or e.g. cPanel “File Manager”:wink:
    – edit the “wp-config.php” file by adding following lines to it, right above the “/* That’s all, stop editing! */” line

    define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );

    – once they are there, please clear cache on site and try visiting any of Defender pages (e.g. “Defender -> Security Tweaks”, “Defender -> Dashboard”:wink: in site’s back-end, preferably a few times

    – after that (again via FTP or cPanel “File Manager”:wink: look into the “/wp-content” folder and see if there’s a file named “debug.log”.

    If it’s there, please strip any sensitive data (like logins, passwords etc) from it if there are any and share the file with me.You can e.g. upload it to some file storage of yours (Google Drive, Dropbox or similar) and share direct download link with me.

    Hopefully, the content of that file will help with diagnosing these issues (or, at least, the “blank Defender pages” one to start with).

    Best regards,
    Adam

      Hi Adam,

      Thanks for your quick response. I have followed your advice, but there is no debug.log in the wp-content folder. I can enter all defender pages. It looks like I can’t empty the cache? see the picture.
      gr. Dick

    Hi Dick,

    That’s strange, I can see the same issue that Adam mentioned, and it seems that a lot of JS files are having errors in the console which is causing this.
    These errors are most likely related to issue with cache clear getting stuck, and I can also see that Divi builder is not loading properly.

    Could you provide us with FTP or cPanel so we can investigate this and see what might be causing this?

    Hi Dick,

    Thanks for sending those in, I’ve checked the installation in more depth and I found an issue inside wp-includes/.htaccess file.
    The security rules in there were doubled up, and it seems that ones were added by Defender, but there was another set of the same ones added by something else, could be a server configuration or if you used a different security plugin before.
    I’ve edited the file and left only Defender rules in there, after that the errors in your WP admin were gone and the dropdown is working as well.

    Can you check it from your end now and confirm if everything is working as it should?

    Best regards,
    Predrag
