Support » Fixing WordPress » Unable to Access Dashboard after Upgrade

  • Initially after updating from 3.5.1 to 3.5.2 I was unable to access the dashboard this became more and more flaky as time went on. I was still able to access through other items on the Dashboard dropdown.

    So I thought that the upgrade to 3.6 may resolve this issue. It appears not. The issue still exists. Since then I have read some of the suggested work arounds like updating the database version number or the missing upgrade.php file but these are obviously now all upgraded to 3.6.

    As an admin I can still work round not being able to access the dashboard however my users will have issues. I have a backup I took before I moved to 3.6 so I am looking for some advice to resolve this rather annoying issue.

    This is the first time I have had a real issue with a WordPress upgrade but it is quite a pain. Any advice is welcome.

    have you tried:

    -deactivating ALL plugins temporarily to see if this resolves the problem. If this works, re-activate them individually (one-by-one) to find the problematic plugin(s). If you can’t get into your admin dashboard, try deactivating via FTP or SFTP or whatever file management application your host provides. If applicible, also remember to deactivate any plugins in the mu-plugins folder. The easiest way is to rename that folder to mu-plugins-old.
    – To rule out any theme-specific issue, try switching to the unedited default Twenty Twelve theme for a moment using the WP dashboard. If you don’t have access to your admin area, you can switch to the default theme by renaming your current theme’s folder in wp-content/themes and adding “-old” to the end of the folder name using via FTP or SFTP or whatever file management application your host provides. Alternately, you can remove other themes except the default theme. That will force your site to use it.
    resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems (because the hooks remain unless plugins completely removed or some plugins stick around in cached files. So by renaming the folder, you break them and force them inactive). Read “How to deactivate all plugins when you can’t log in to wp-admin” if you need help.
    – If the above troubleshooting steps fail to resolve the issue, try manually re-uploading all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones. Read the Manual Update directions first!
