   My blog: http://www.jeanlucbenazet.com/blog/

   I have decided to update to the latest version today from 2.7.

   After the installation and the upgrade of the database, i noticed all my plugins were deactivated, so i tried to reactivate them again, and got the following error:
   --------------------
   Warning: in_array(): Wrong datatype for second argument in /usr/local/psa/home/vhosts/jeanlucbenazet.com/httpdocs/blog/wp-admin/includes/plugin.php on line 310

   --------------------------
   Worse, I tried to change the Theme, and suddenly i'm told all themes are broken, and suddenly my blog changes to a blank page!

   Can anyone help? I'm not very technical... even though i managed to fix bugs in the past. This one is going over my head :(

   Thanks
   Jean-Luc

   You'll probably have to re-install.

   Remember to always deactivate plugins BEFORE upgrading!

   I've reinstalled in a new directory, I get exactly the same errors! :(
   Have i screwed my whole blog !? Any idea? Is it the database?

   Try resetting the plugins folder by FTP or phpMyAdmin? Sometimes, an apparently inactive plugin can still cause problems.
