--------------------------------------------------------------------------------------------------------------- Originally i was using 1.1.1.5166 over mysql 4.1.20. Changing the skin works fine here. I am testing xwiki 1.4 before we put it into production, so i loaded up the database dump from from the production xwiki (v1.1.1.5116) onto a server running mysqI 5.0.58 and xwiki v1.4.9828. Thats where i get the stack trace. I also noticed that with the Toucan skin, the administration tools are messed up. No users/groups show up when you click the tab on the admin page. but when i change the skin to albatross the users/groups show up. Any help is appreciated. Thanks! Marlon
