I am getting this error. Fatal error: Call to undefined function: add_filter() in /hsphere/local/home/mistaong/westerncivtogo.com/wp-includes/default-filters.php on line 20
Apparently a very common one with the new upgrade. I searched the forums and found several topics with no reply and some with replies but no fixes that when implemented actually worked or I am not enough of a geek to understand. Please help. I am trying to upgrade after having 2 blogs fall victim to a hacker and I need to get them back up and running. Seeing the frequency of this bug I would urge the wordpress team to look into whats happening. Thanks!
