[wp-testers] error 500 after upgrade to 2.5.1

[Dispoweb2.0[Ghaith]]

 Hello,

I decide to update my wp 2.5 to the new one 2.5.1, I download it from
fr.wordpress.org and make the necessary to update my website, i try to
access to the dashboard to update and do it well but when the update
finished I try to access to my website and get a 500 error.

I'm staying looking for the problem but don't get any solution to fix that.

Cheers,
Ghaith
