    Warning: call_user_func() expects parameter 1 to be a valid callback, no array or string given in /home/newmind/public_html/wp-includes/functions.php on line 2599

    I’m using the plugin in on a Multisite stall. It’s already authorized on another site within my install.

    I get the error above when I click “Allow” at eventbrite.
