Support » Fixing WordPress » Can't access dashboard after 3.5.1 to 3.5.2 update

  • Resolved rnewkirk


    I’m having a similar problem that a few others have posted about. Can’t get to dashboard, and am getting a 404 after updating from 3.5.1 to 3.5.2. Have tried clearing cache, disabling all plugins via FTP by renaming plugin folder to “plugins-old”, etc.

    Has anyone found an actual fix for this?

    edit: to explain plugin disable method.

    Using FTP/ cPanel deactivate your plugins’ folder by adding -hold and see if it helps to login.

    thanks for the quick reply Krishna. But in my orig post I mentioned I’ve tried that, and it had no effect.

    You didn’t mention you had tried that method. If you have tried other methods can you let us know, preferably in your first post?

    Found a solution from this thread:

    If you are getting the error, this worked for me: Navigate via FTP to your installation. Check to see if the upgrade.php file is there. If not, download WordPress 3.4.2 from Unzip the download and navigate to the wp-admin folder. Locate the upgrade.php file and FTP it to your installation. Somehow the in-app update process download was corrupted and missed the required upgrade.php which the redirect points to after the update. Good luck!

    Looks like for me, the upgrade.php file was missing from wp-admin folder. Downloaded 3.5.2 from, then FTP’d upgrade.php. It then prompted for a database upgrade, and I’m back in action.

    Thanks to chowsir for the fix, and Krishna for quick response.




    Great! 🙂

    It works for me!

    rnewkirk (and chowsir and Krishna) – you saved my bacon. Even this non-techie could follow the easy instructions. I’m back into my dashboard and very grateful for your help.

    I had to go and downgrade back to 3.5.1 and then update ALL plugins then update WP
