We are running Moodle 2.7.9+ on RHEL 6.6 with PHP54, HTTPD-2.215, and Mariadb55.
Mnet worked flawlessly for us until recently when
we have started integrating with Banner system. LMB(Luminis Message Broker) plugin was installed and users account with different profile settings were created. As part of the integration CAS SSO also is enabled. To prevent users from editing the "email" line of their profiles, user/editlib.php was edited.
Now when we try to Mnet enroll our users into other Mnet enabled courses in an affiliated sites, we get a blank "Course summary" screen. Please see attachment
We 1.)disabled CAS SSO, 2.)removed changes in editlib.php, 3.)tried to enroll with the new and old user profiles, 4.)tried different browsers, 5.)tried different Mnet sites and yet nothing can make Mnet to work again.
Any insight or clue would be greatly appreciated!
It is related to memory_limit in /etc/php.ini.
After increased its value, Mnet enrollment is working again.
