WordPress MU

Today I have tried to update wordpress, but after I uploaded all the Files the Site shows only a blank screen.
How can I fix this, need help.
Thanks in advance for your answers!

Have you checked the error logs? Page source in your browser? You didn't write over your config file, did you?

Which error Log do you mean?
The source code of the blank site is empty.
I've merged the changes to the new config sample and have overwritten this one on the server.

It should be your wp-inst/wp-includes/kses.php file. I have the same problem as well when you try to upload all the files.

'div' and 'p' are missing the closing tag ')'

The error logs are in your cpanel file manager area.

It's fixed now, update from svn or download the nightly later

Nice, no problems any more :)
