Hello I am getting a fatal error when trying to activate
Plugin could not be activated because it triggered a fatal error.
Fatal error: Call to undefined method scbAdminPage::register() in .../plugins/wp-useronline/wp-useronline.php on line 83
I tried to uninstall pagenavi but that didn't help.
Any solutions for this one.
WP 3.5 Multisite and I have several of your plugins installed but not all active on the site I am trying to activate WP-Useronline on.
