Learners unable to enroll and enrolled courses not showing up on dashboard

Hi everyone,

I’m pretty new to OpenEDX. I was able to deploy an instance in a virtual machine and it seems that is working correctly. But when a user tries to enroll in a course it’s not getting enrolled. And when the user goes back to the course he just tried to enroll, it tells him he is enrolled but it won’t show up on the dashboard. The dashboard shows You are not enrolled in any courses yet.

Any help? Thanks in advance
