Support » Networking WordPress » Fatal Error message

  • I’ve been using WordPress MU for many years now. Updated the latest version a few days ago. Everything has been fine. I was logged into one of the sites and went to add a plugin via the Network admin. Got this error:

    Fatal error: Call to undefined function wp_get_current_user() in /home/clubhou1/public_html/wp-includes/capabilities.php on line 522

    Anybody have an idea how to correct this?

  • That error means that WordPress hasn’t loaded yet. Have you deactivated all plugins, reverted to a default theme and tried again?

    Looking further into it, I suspect I’ve conflicted WordPress with two passwords on the same Admin email address. In otherwords, I’ve logged into one of the sub-sites using the same email address the Network Admin uses, but with a different password.

    I fear screwing this up in trying to fix it. I need confirmation, then some firm guidance on what to do next…

    Ok, I grew impatient waiting for more insight into this issue, so I tried the advice of danhgilmore. I changed to an old WordPress theme, then deactivated my plugins (save those that were Network activated).

    Bingo, I’m back in as Super-Admin on the Network site.

    Thanks much, danhgilmore. Appreciate your keen insight. 🙂

    Yes, see, there is a reason we always recommend deactivating plugins and trying a default theme. This is because it often works. 🙂

    Reactivate things one at a time until you find where the problem originates from.
