Why does it say enrollment closed when my students click the code to join?

[SFG315]

I have two courses--one for seniors and one for sophomores. The link to my seniors works fine, but the link to my sophomores says "enrollment is closed". I am not sure why and I cannot seem to figure it out.

@SFG315 It's possible the issue is in the settings for the course; check the start and end dates of that course to make sure it's still available to students.
