Support » Plugin: Fast User Switching » Error when switching to another user

  • supertiny


    When i try to switch to another user from the admin account in the admin topbar, I get this error:

    Fatal error: Call to undefined function is_plugin_active() in /home/serahlee/public_html/staging/wp/wp-content/plugins/fast-user-switching/fast-user-switching.php on line 684

    May I know how to resolve this?

    Thank you for your feedback, we’ve checked this plugin in the WordPress new version 5.1 and the earlier versions, but we can not see any problem here, even this function(is_plugin_active()) is working just as well.

    Will you update your WordPress version?

    If you still have problems then let us know. Another thing please let us know about your WordPress+PHP version of details.

    Thank You,
    Tikweb Team

    Return back-the error disappears. The selection of the second user sends tо first.
