Hi @msjenniferdawn,
I’m sorry you’re having this issue!
Can you provide us a copy of your System Report: https://lifterlms.com/docs/how-to-use-the-lifterlms-system-report/ using the WordPress guidelines for posting code: https://www.ads-software.com/support/forum-user-guide/faq/#i-need-to-post-code-is-that-okay and also screenshots of the issue you’re seeing using a service (Dropbox, Drive, Imgur, CloudUp, etc…) and post a link to your screenshots.
Just looking at your shop page it doesn’t look like you have any courses set up at all. I also don’t see a course catalog or membership catalog that would be associated with LifterLMS. Do you have all the required pages set up for LifterLMS to work: https://lifterlms.com/docs/lifterlms-required-pages/
If so this may be a plugin conflict, but I’d need to see the System Report to tell what could be happening!
If you can provide us with this information we can look into the issue further!
Let us know if you have any further questions!
Thanks and take care,
