    Just did an update and now I am trying to log into my site and getting the following:

    Fatal error: Call to undefined function nf_is_func_disabled() in /home/familyl6/public_html/wp-content/plugins/ninja-forms/deprecated/includes/admin/upgrades/class-upgrade-handler.php on line 32

    Any fix for this?

    Hi Kevin,

    It looks like it’s an error related to Ninja Forms. Specifically this function:


    is not spelled out anyplace, but the Ninja Forms updater is trying to use it on line 32 in one the plugin’s files. That’s causing the fatal error that you’re seeing.

    If you can still log into your WordPress dashboard, try disabling the plugin and see if it doesn’t fix the error. If you can’t log into your WordPress dashboard, then use either a FTP program or your web host’s control panel’s file browser to go to the wp-content/plugins folder and delete the folder for Ninja Forms there. That will disable the plugin and should let you log back in.

    Hope that helps out,
