We are migrating our jForum 2.1.8 running on MySql to version 2.1.9 running Oracle 11.2.0.3.
I have succesfully migrated all data from MySql to Oracle, and the forum is running without problems as long as I'm not logged in (see picture 'Not logged in').
Postings etc. all display with out problems when I'm not logged in.
When I log in I get a null pointer exception (see picture 'exception').
