My Enrol users button has stopped working in all courses for the System administrator. It was working before I took these steps today:
I have been trying to figure out how to enroll students in multiple courses at once. Today, from some reading I did, I thought the User bulk enrolment plugin might work. After installing it, I realized it was not going to do what I wanted, so I uninstalled it.
I then tried to enable the category enrolments plugin (using these directions: https://www.xelium.co.uk/2015/06/3-steps-to-enable-configure-category-enrolment-in-moodle-for-role-management/). I moved many courses into categories, but not all. It might work, but in the process of testing it, I discovered the Enrol users button now is unresponsive when I click on it. It does absolutely nothing. It doesn't matter whether I pick a course that was moved to a category or not, the button works nowhere. I undid the steps in the link, but the button still will not work. I don't know which plugin caused the problem, or what setting I need to change to get the Enrol users button working again. What do I need to do to fix this?
