Just upgraded to 2.5. Nice BTW but, I am receiving this error at the top of each post:
"Warning: array_key_exists() [function.array-key-exists]: The first argument should be either a string or an integer in /home/myfault/public_html/wp-includes/category-template.php on line 192"
This would seem to suggest a coding error, but I am not a PHP guru.
While this appears at the top of each post, clicking on that post displays properly and all else seems to be working fine.
