I was trying to install a slideshow plug in and entered a line of code into the wordpress page, and now this is all that happens when I try to go to the site. I can no longer log in or anything.
I didn't create this site under my log in. I created it from their domain host, Fat Cow. The only way we have been logging in is from the actual site at the bottom I put an admin login.
Fatal error: Call to undefined function is_user_logged_in() in /hermes/waloraweb089/b2747/moo.baxterbethanyuccorg/wp-includes/query.php on line 2485
How do I get back into the dashboard?
