Hi @wanghaibing ,
> If the user has not yet started any course yet and click start a new course in the “My Courses” page, it goes to an error page stating that “Perhaps you can try a new search.
That error does not exist in Sensei, but seems to below to OceanWP: https://github.com/oceanwp/oceanwp/blob/master/404.php
It’s possible that there might be a conflict with one of your current plugins or your theme.
Try disabling all of your plugins except Sensei LMS (and extensions). Then try testing again to see if the issue persists. If that resolves your issue, you can find what was causing it by enabling each plugin one by one while continuing to test.
If that doesn’t help, you can also try switching to the Twenty Twenty theme via Appearance > Themes, and test again. If the issue is resolved then you know it’s a problem with the theme, and you’ll need to contact the theme author for further assistance.
Best,
