Hallo, thanks for the reply.
Unfortunately i couldn’t solve the problem with P2 theme and my LAMP setup. Unistalling/Reinstalling and renaming class in the php-code does nothing and apparently only the P2 theme is affected…
Now Im running wordpress+p2 on another machine with a different LAMP setup (which runs older versions of php5/mysql) and I didn’t run into any probs with P2 theme.
There must be something wrong with my LAMP config on the 1st machine, though i cant figure out what it is, since everything else related to apache/php/msql works as it should.
Oh well…
