Bug Trac
#5284 (Editing & Posting Comments Causes Errors) – WordPress Trac – Trac
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ’sanitize_url’
I had the same error when posting a comment, and bbbburns had it when trying to view my RSS feeds. Apparently I had an incomplete upgrade for my formatting.php file in wp-includes. Fixed now, comment away!
