All of the sudden when I try to go to the dashboard or wp-admin on my blog I get:
Fatal error: Call to undefined function: error() in /home/isomd/public_html/journal/wp-includes/rss-functions.php on line 79
The blog proper shows up but I can't get to the admin area. I searched the forum but what I found did not seem applicable. I'd appreciate any help I can get. Thanks!
