I finally tried upgrading to the latest version of WP after not updating for over a year. I backed up my files, thankfully, because I had to restore them after the patch (upgrade) failed. I got the message: Fatal error: Call to a member function on a non-object in /home/content/a/n/a/analiese/html/wp-includes/taxonomy.php on line 289
Now when I go to login to wp-admin I get this message:
Database Upgrade Required
Your WordPress database is out-of-date, and must be upgraded before you can continue.
The upgrade process may take a while, so please be patient.
Any advice? I'd still like to upgrade but also need to just login to post. Thanks!
