[otrs] Theme incorrect after upgrade to 1.3.3

Hi, I just upgraded my otrs from 1.2.3 to 1.3.3. I always used the "default" theme. But now If I log in to otrs No theme seemed to be loaded. The top line of the webpages is "$Include{"Copyright"} $Include{"css"}" Is this a permissions issue? Or do I need to do something more about these theme. I noticed the line in the UPGRADE document "the otrs themes between 1.2 and 1.3 are _not_ compatible". I've no clue how themes are managed by OTRS, the default theme is sufficient, so how can I reset this? -- Met vriendelijke groet / With kind regards, H. van Wees --- The official Gentoo motto is, "If it moves, compile it."
