So I recently took to upgrading our site to 3.4.2, at first through the automatic tool and then later by manual updating it.
Upon updating the site everything seems to work fine but every time I try to access the wp-admin/ sub-page I'm greeted with:
Database Update Required
WordPress has been updated! Before we send you on your way, we have to update your database to the newest version.
The update process may take a little while, so please be patient.
To which I click the "Update WordPress Database" which leads to a blank page with a WordPress logo and blank box. And despite manual and automatic updates to the wordpress files, this page still remains.
I have been trying everything I can think of. I have tried deleting the upgrade.php file which results in a 'page not found' error. I have increased my php limit from 20M to 99M, I have cleared my cache and such, different browsers, I have tried waiting.
I added "ini_set('memory_limit','99M');" just inside the opening PHP tag in wp-admin/upgrade.php. I even went to wp-config.php and set WP_DEBUG to TRUE to see if I was getting any errors. No errors in wordpress, no errors from the host.
I tried switching to the Twenty Eleven theme by renaming my current theme's folder inside wp-content/themes and adding "-old" to the end of the folder name. I tried resetting the plugins folder via FTP. And I have re-uploaded all files except the wp-content folder.
Despite all of this, the problem remains. Any other ideas?
