    Hey there! If you're quickly refreshing pages or navigating the site, sometimes Apache can detect this as malicious traffic. Is there anything additional next to the "client denied by server configuration" message in the Apache log? You may want to check if your machine has mod_evasive installed in EasyApache, which you can do with this command: rpm -qa | grep -i evasive
    or you can check the Apache Modules section of the EasyApache 4 interface in WHM. If this is present, you may want to try removing it and then see if you're still able to reproduce the problem.

    Typically we don't recommend much tuning for that module, but you can adjust advanced options as outlined here:

    Hello, I had the same problem with a WordPress installation (client denied by server configuration ... /wp-admin/admin-ajax.php) and disabling mod_evasive Apache module fixed it. Now I've got another error in /usr/local/apache/logs/error_log : [Fri Mar 26 01:39:58.523102 2021] [access_compat:error] [pid 829604] [client x.x.x.x:53172] AH01797: client denied by server configuration: /home/xxx/public_html/wp-content/uploads/woocommerce_uploads/, referer:

    That seems like it could be a permissions/ownership issue. Do you see anything odd with ownership or permissions anywhere in that file path?

    Hey cPRex, It looks like a security measure taken by Wordfence (WP security plugin) in .htaccess in order to avoid execution or something the like. It's ok. Thank you for your help. Best regards, Mauricio
