Comments Not Showing Up

All the comments on every page no longer show up, and have not been showing for quite some time. I linked one in particular with over 100 comments, but now they show as lines and nothing else. People can still comment, I can still approve the comments, but nothing shows in the end on any of the pages. Previous comments also are still on the backend pages, but they don’t show on the website anyone. Is anyone else dealing with this? Is there a fix? Thanks so much for the help!
