After auto upgrade to 3.3 I receive the following message when attempting to access the dashboard:
Fatal error: Call to undefined function is_rtl() in /home/secrev/public_html/wp-includes/general-template.php on line 2102
Please help... It looks like other had a similar problem and deleting a file worked for them. Would I need to do the same thing? Please name specific file.
Thanks for the help,
