Courses disappeared from LMS

Seems like plugins are outdated . Please update your wplms theme and all its plugins altogether to avoid any conflicts . Then please re-save the permalinks and clear browser cache .

Please share admin credentials and site url to check this at your end . Ps: mark reply as private while sharing the credentials  .

This is a very unusual issue. In fact this is the first time it has been reported so far. Yes it could be related to outdated plugins and updated theme. Please share your site url, I am unable to locate it.  

I checked your site and found that there is no curriculum is set in your course . and the error appears on the instructing course page when there s not curriculum is set in your course . Please try adding atleast one section and unit in your course . ALso i was able to see all the units in teh wp-admin -> lms -> all units and also on all courses page .

That would not be possible with the update. Update just replaces the old files with new ones in your wp-content folder . It does not affect the database at all . and the course and lms content are saved in database . Please try contacting your webhost on this and check if you can restore the content with  the help of database backup .
