Hi all, I am so shocked this morning to see the courses in my moodle 3.4 suddenly have empty participants list.
I am logged in as admin.
I am in developer mode, no errors appear, nothing on my apache/php/mysql logs either.
The same time none of the settings buttons work, i can list on enrol and add users, yet they dont appear on the site. What has suddenly happened? The weird thing is, when on this page, even my left nav drawer does not work.
If i click reload/refresh button on the browser it loads fine.
I have done clearing the browser history & purge moodle cache, it is still the same.
How can I resolve this problem?
