Thanks for your help! After this, I also had to reinstall extensions 
from typo3conf/ext to get things working. I ignored warnings from 
tt_news about my PHP version (too high - I'm using the latest PHP5 when 
it wants 5.0.4 or something) and Typo3 version (should be 3.8.1).

When doing the update wizard, I was forced to run it twice, so I'm not 
running in 3.8.1 compat mode as far as I can tell. Would there be 
anything to look out for such as problems with using 4.0 and extensions 
made for 3.8.1 or should it be smooth sailing from here?

Cheers!
