Dear all,<br>
<br>
I&#39;m quite a OTRS newbie - of course I wanted to keep my system upgraded and tried to upgrade from 3.1.4 to 3.1.5 (the steps described in the documentation guided me through the upgrade).<br>
<br>
Unfortunately now my OTRS installation displays an internal server error 500 and the error_log reads:<br>
<br>
[Tue May 15 11:22:36 2012] [error] Can&#39;t locate object method &quot;new&quot; via package &quot;Kernel::Config&quot; at /opt/otrs//Kernel/System/Web/<u></u>InterfaceAgent.pm line 76.\n<br>
<br>
Does anyone have an idea what could&#39;ve went wrong? Where I can continue searching (and fixing) the problem?<br>
