  Yes those rules are known to cause a lot of issues and I rarely use them. I normally use these Deploy Comodo ModSecurity Rule Set in cPanel, Comodo Web Application Firewall v2.4, Firewall Software

  Hi @Paul Shultz You might also want to identify the specific rules that are causing the issue and just disable those in WHM>>Security Center>>ModSecurity Tools -> Rules List Something to keep in mind that while the Comodo ModSecurity Ruleset is great it is a 3rd party vendor and not something that cPanel is able to provide support for. Thanks!

  Just an update on this. The problem does not seem to mod_security at all. The profile I had, which is built on mod_http2, mod_proxy and mod_mpm_worker ...., simply causes many log entries as per below [:error] [pid 7795:tid 47939049174784] [client xx.xx.xx.xx:50435] client denied by server configuration: /home/xxxxxx/ Little or no log entries to diagnose further, so have reverted back to non mod_http2. Its a pitty I wanted to make use of http2, but cant find a profile that works.
