Hello,

Do you have any customizations done to the cPanel theme or webmail interface? Furthermore, is this the only error output in the cPanel error logs in relation to this'?

Hi Lauren,
I don't have customizations to the cPanel theme and webmail interface. This is the only error output relate to this error. Access by Horde theme is normal, just error first time login with roundcube like I said before.

I was referring specifically to errors in the cPanel error log in my previous response. Can you please provide me the full log information related to this if there are further logged errors.
