The last course published appears in the course menu with this link
www.mydomain.com/members/"name of instructor"/"name of course"
Alex told me: "This was an issue with the title of the course directory page and we fixed this in the latest update of wplms theme 2.0 .
Please update your theme and all its plugins to the latest .Re-save the permalinks and clear browser cache after updating .
If still you are facing the issue then please create a new course directory page and assigne this page in settings -> buddypress -> pages -> course directory page ."
I did that and the problem war repaired but later the issue reappeared.
After update the problem continue
Please note that there was an issue with the course permalinks in the previous update of wplms .
When the course peramalink settings are not set to the default then the any of the course tab wont work .
We have fixed this issue in the latest update of wplms theme and vibe course module plugin .
Please update the wplms theme and all its plugins to the latest .
If issue still persists then please share admin credentials and site url to check this issue at your end .
