Upgraded a pretty large site from Evoq 8.0.1 to Platform 9.2.1. Actually, still upgrading at the moment. It's a site that once started out in DotNetNuke 3. Upgrade to 9.2.1 didn't throw any errors. Had to fix a few skin issues but then I was able to login.
However, the personabar isn't showing. The first call it does, is to API/personaBar/localization/gettable?culture=nl-NL
This call returns a 500 (internal server error).
