I tried to perform an instant upgrade to WP 2.8 and my process page said "done" even though there was no indication that the different steps (downloading upgrade file etc) were being completed. I refreshed and nothing changed so I thought maybe my IE browser wasn't responding. I closed the tab and when I returned to the wp admin url, I received the following error instead of the sign in form:
Fatal error: Call to undefined method WordPress_Module::_weak_escape() in /home/majorla/public_html/wp-includes/wp-db.php on line 487
I am unable to sign into my dashboard at all and my home page also shows this error.
My hosting control panel works as does the site's email. How do I restore the backup or otherwise obtain access to my dashboard?
I was unable to gain access through FileZilla as well. I get the following error through FileZilla
530 Login authentication failed
