[Irwansyah Ramadhan]

Hi, i can't access my WHM. After login, a warning message always showed. I had upgraded my cpanel to latest version but it's still the same.
This is the warning message:

A warning occurred while processing this directive.

Hello,

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.

Hello,

To update, internal case CPANEL-11981 is open to investigate this issue. It looks like this is affecting certain systems on the development build for cPanel version 64 (currently only available on the EDGE build tier). I'll update this thread with more information on the status of this case as it becomes available.

Thank you.

Update: It looks like this will no longer occur as of cPanel version 66.
