Yesterday I updated to 3.3 without backing up my files. I can now see my website (www.hubplan.com.au) but I can't access my site via /wp-admin (interestingly I can still see WP on my iPad and iPhone.
I've followed and attempted all the other similar tips and advice, including:
- Try re-uploading all files & folders - except the wp-content folder - from a fresh download of WordPress.
- Delete cache.
- Clean Install
- Tried all the same through the FTP
- Confused myself with mysqladmin stuff.
- Tried to delete the 'Maint' file in wp-admin (It wouldn't let me)
Now I'm waving the white flag and need some help if anyone's got time.
The error I get is:
Fatal error: Call to undefined function get_current_screen() in /home/hubplanc/public_html/wp-admin/includes/dashboard.php on line 149
