I have 3 instances of OTRS 3 of them is 4.0.5 and the last one is 3.2.13 I have the same links in /opt/otrs/Kernel/config.pm: [ 'UserLogin', 'BitAdmin', 'uid', 1, 1, 'var', 'https://xxx.xxx.no/employee/exact/$Data{"UserLogin"}" TARGET="_blank"', 0 ], After upgrading to 4.0.X the links got broken The links work well in OTRS 3.2.13: https://xxx.xxx.no/employee/exact/userlogin In OTRS 4.0.5 it is broken: https://xxx.xxx.no/employee/exact/$Data%7B Anyone knows how to fix this?
