Makes me think you have a plugin or theme that is not 2.3 compatible or that you didn’t get a complete and good upload of the 2.3 WordPress files.
Please note the sticky threads about database problems.
@michael H: I already mentioned that its caused by the theme i use. Why is there never before mentioned that you should have a 2.3 ready theme before uploading?
@arnee: thats a thread with problems, I need solutions
Overwriting the files like the short Three Step Upgrade says doesn’t work in this case. Removed all files and uploaded the files again. Now it works fine. Case closed. (thanx MichaelH for pointing in that direction)

Because if your theme had been written correctly in the first place and didn’t use direct database calls, then it would work fine.
There’s always a way to write things that will be incompatible. Themes, plugins, anything external to WordPress can break with *any* upgrade. There’s no way to know what themes will break, because there’s tens of thousands of them.
But for future compatibility, here’s a tip. If you see a theme that contains SQL code, then it’s quite likely to break at some future point. Avoid using it. Plugins often use SQL code, but if they’re using that code to access normal wordpress tables (instead of their own tables), then they’re at risk too.
