Our current OTRS is on version 3.1.12 running on Fedora 9. I have found out that it is impossible to upgrade Fedora to newer than version 15 (or was it 16?). So I have setup a Centos 7 machine in a lab environment and successfully installed version 3.1.12, imported the database and step by step upgraded to version 6.0.6 of OTRS.
Most things works, but there's one thing I cannot figure out. Replying to an email seems to be disabled. In the screenshot below "Svar" is norwegian for Reply.
I have googled, searched this forum and browsed through what feels like every setting but I cannot find out why. I hope someone here can point me in the right direction.
