Hi All, I'm having a slight problem after upgrading from 2.2.4 to 2.3.3 on a CentOS 4 (RHEL4) machine. I get the following lines in '/var/log/messages' quite often. Oct 27 09:57:43 tao OTRS-CGI-10[31841]: [Error][Kernel::System::Cache::Get][Line:137]: Need Type! Oct 27 09:57:43 tao OTRS-CGI-10[31841]: [Error][Kernel::System::Cache::Set][Line:105]: Need Type! I thought it was just happening when I used the web front end at first, but it seems to happen pretty regularly most of the time (though not associated with any cron job as far as I am able to tell). Doing the upgrade I just copied the new release files over my existing installation, and ran the database upgrade scripts as mentioned in the UPGRADE readme. I deleted the old /var/cron/ directory contents since it seemed like many of the old cron jobs were no longer being used. I also tried the upgrade by just creating a new directory for OTRS and copying over my old Config.PM file but then it complained that nothing was registered in Config.PM everytime I clicked on a link on the web front end. Does anyone know what the origin of these messages are? Are there stale cache files that have to do with OTRS that are causing issues? Thanks for any help!
