Hi @bluestandish,
Are you referring to modules in backend while creating your units or something on the front end after the course was created?
If something is not loading it usually means that there’s some script breaking up and it’s most likely a conflict issue.
Can you check for conflicts by disabling your other plugins and switching to default WP theme to see if it works after that?
If the issue is still there after that can you open the page where the issue happens in Chrome and bring up browser console by pressing Ctrl + Shift + J on Windows or Cmd + Option + J on Mac.
If there are any errors they should show up in console and that should help us with pinpointing the issue.
Cheers,
