"Warning: call_user_func (ArtistDataPress_Plugin::url_section)

Hello! I love the way this plugin looks on other sites, but unfortunately it’s not working for mine: http://merciesmusic.com/live/ (look below the bandsintown feed)

The feed for shows is: http://feeds.artistdata.com/xml.shows/artist/AR-1B488CBA3E97A2A0/xml/future

The ArtistData profile page is: http://artistdata.sonicbids.com/mercies/

I have checked with GoDaddy to make sure PHP safe mode is OFF. They said “by default, Linux hosting keeps the PHP safe mode off”. I can’t access the root via super user in SSH because it’s a shared server. But if GoDaddy says it’s off, it must be off…….

Nonetheless, here are the warning messages I see in the ArtistDataPress settings page.

Right under the “ArtistData URLs” it says:
Warning: call_user_func(ArtistDataPress_Plugin::url_section) [function.call-user-func]: First argument is expected to be a valid callback in /home/content/28/7703428/html/wp-admin/includes/template.php on line 1102

Under the “ArtistData Display Options” it says:
Warning: call_user_func(ArtistDataPress_Plugin::display_section) [function.call-user-func]: First argument is expected to be a valid callback in /home/content/28/7703428/html/wp-admin/includes/template.php on line 1102

Then right below “which styling do you prefer” it says:
Warning: call_user_func(ArtistDataPress_Plugin::styling_preference_fn) [function.call-user-func]: First argument is expected to be a valid callback in /home/content/28/7703428/html/wp-admin/includes/template.php on line 1138
