Moodle 2.7.1. With OpenMeetings server 3.0.4 and OpenMeetings Moodle Plugin 1.7.2 the link that is supposed to list all OM activities in a course ( ) leads to a blank page. Turning on DEVELOPER debug output produces: Fatal error: Call to undefined function get_record() in /var/www/moodle/mod/openmeetings/index.php on line 34
the OpenMeetings developer has fixed this issue now. Please download the latest version of the openmeetings plugin for moodle (Version 1.7.3). It should work with moodle 2.7 & 2.8.
Thanks for the bug report & Greatings,
