    Seeing this error in Apache error logs. Following is the complete error message.
    Code:
    [Thu Feb 23 12:38:23.367696 2017] [core:error] [pid 466789:tid 139681249302272] [client xx.xx.xx.xx:51322] AH00524: Handler for (null) returned invalid result code 70008, referer: http://sample-domain112.com/wp-admin/theme-editor.php?file=header_backup.php&theme=Minimal
    
    The error happens when trying to edit the file header_backup.php from the Appearance > Editor option in WP. Not sure what is causing this issue. The mod_security has been disabled in the domain.

    Hello,

    You can browse to "WHM » Service Configuration » Apache Configuration » Global Configuration" and see if increasing the "Max Request Workers" limit helps to address this issue. Per it's description, this directive sets the limit on the number of simultaneous requests that will be served.

    Thank you.

    Hello,

    Thanks for your update.

    I have tried increasing the "Max Request Workers" limit from the default value of 150 to 200. But the issue still remains. The error message also seem to be the same:
    Code:
    [Thu Feb 23 21:52:54.266520 2017] [core:error] [pid 579274:tid 140707989772032] [client x.x.xx.x:37392] AH00524: Handler for (null) returned invalid result code 70008, referer: http://domain.com/wp-admin/theme-editor.php?file=header_backup.php&theme=Minimal

    It's difficult to know for sure what's causing that error message without reviewing the system. Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome.

    Thank you.
