SOLVED Mod Security rule changes in cPanel 64

[jndawson]

We just got the 64.0.1 update last night.

We're also having issues with installed SSL certs that aren't working. For example, our WHMCS system won't allow log ins and the cert won't display.

Update - We think it may be related to the mod_sec update:

Update:

The v.64 update changes the path for php temp sessions from /tmp to /var/cpanel/php/sessions. We had
'Jail Apache Virtual Hosts using mod_ruid2 and cPanel® jailshell' set to 'On'. Turning to off corrected the session errors and a bunch of other things.

Thank you, cPanel people.
