OTRS 5: Fatal Error Kernel/ Modules/ AgentTicketZoomTicketID

Recently we switched from http to https for our ticket system OTRS5. After doing so, clicking on the links OTRS sent via email in (customer) notifications, resulted in the error:

Module Kernel/Modules/AgentTicketZoomTicketIDxx.pm not in @INC (/opt/otrs/Custom /opt/otrs/Kernel/cpan-lib /opt/otrs/ /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl

After some digging, we traced the problem back to Apaches RewriteEngine which replaced the “;” chars with “%3b” when someone used a http link (which OTRS sent via email).

The solution was simple: Set HttpType to “https” in SysConfig -> Core.
