 * I updated to version 2.8.5 and now my plugins don’t work.
 * When I try to activate them, I get this error message.
 * Warning: in_array() [function.in-array]: Wrong datatype for second argument in/
   mnt/w0502/d02/s30/b026c564/www/blog/wp-admin/includes/plugin.php on line 310

 * I’ve tried a couple of the suggestions posted on the forum. I’ve deleted any 
   spaces in the plugin.php and pluggable.php. I’ve deleted all the pluggins and
   uploaded them individually and none of that has worked.
 * Any help would be greatly appreciated!
