Try:
– switching to the Twenty Eleven theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.
– resetting the plugins folder by FTP or phpMyAdmin.
– re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress.
– running the upgrade manually via wp-admin/upgrade.php
Sorry about my ignorance Esmi but I have to ask before proceeding. Do I have to do ALL of this or just ANY of this? :s
Yes. Every step in that order.
Thanks Esmi, I just did it and seems is all working again. 🙂
Esmi, could you explain the step “re-upload all files & folders”? I tried installing a new WP in a different location on the server, then moving the files over, but that did not work.
Thanks!
