Support » Fixing WordPress » Cannot access WP 3.51 after upgrade

  • We have upgraded from 3.4 to 3.51 without incident for a few days, then lost the ability to log onto WP as admins all of a sudden (any and all accounts). The web interface just hangs when we try to log on, and it does the same when we try to reset our passwords. Has anyone encountered this issue before?

  • Hello Andy,

    It is most likely a javascript issue caused by an incompatible plugin or theme.

    Here are the steps to find out if it is plugin or theme related:

    1. Deactivate ALL plugins. Yes, all of them.
    2. Switch to the default twentytwelve theme.
    3. VERY IMPORTANT – Manually empty your browser cache. If you don’t know how.. Google is your friend.

    Now, after you have manually cleared your browser cache… log back into your admin panel.. and see if you still experience the same issues.

    EDIT: You may also want to give the 3.5 Master List a read… as it addresses a few issues as well.

    Thanks so much for the fast response, Josh. we can’t log on to the admin console however to make these changes. Can we makes these changes directly to config files, and if so which ones?

    Using FTP or your hosts cPanel.. you need to access your file directories.

    Browse to the “wp-content” directory.

    Once there… rename the “plugins” directory to something like “plugins-testing”.

    This will “force” all of the plugins to deactivate.

    Now… see if you can login to your dashboard.

    That may have fixed it. Thanks for you assistance, Josh.

    How can we re-enable the plug-ins? Is this a known non-compatibility issue with certain versions of IIS or PHP? Can we re-name the plug-in directory back to it’s original name?


    Well, WP changed quite a few things with 3.5. A lot of plugin and theme developers had to make changes in their software to stay current with WP.

    Unfortunately, a lot of plugins in the WP repo (and elsewhere) get abandoned with time for one reason or another. So, if you were using an “abandoned” plugin… then it will most likely break.

    So, now that you can log in… you need to start re-enabling your plugins a few at a time. If it breaks, you know it’s one of those last few you activated. If it doesn’t, activate the next group of two or three.

    Basically, what you are trying to do is determine which plugin is breaking your website.

    Got it. Thanks a lot. You’ve been a huge help.

    Please let us know what you find out.

    PS: Yes, you will need to rename the plugin directory back to “plugins”. But, it might break again. If it does… you’ll need to open the “plugins” directory and add something like “-test” to each of the plugin directories.

    Then, remove the “-test” from a few at a time.

    I know it’s a HUGE pain… but, it comes with the “price” of open-source software 😉
