I just upgraded my WordPress installation to 2.3, and now on the website I am getting some code showing.
This is what is showing.
Warning: array_key_exists() [function.array-key-exists]: The first argument should be either a string or an integer in /home/charleu8/public_html/analyzingdiets/wp-includes/category-template.php on line 176
Would appreciate any help. I am not very technical on fixing coding, but can follow directions well.
