Comments dissapeared but showing in Database

I'm having a problem I can' figure out, I hope you can help.

This morning I published an article under which several comments were placed. I could read them and everything worked fine.Then all of the sudden, the number of commens were still showing on the article, but they were not in the comment section of wordpress any more. Now it shows 0 comments and they do not appear in the valid comment sections, nor in SPAM, TRASH, etc. When I go into the phppanel and look in the database however, they still are there.

How can I fix this? Is there anyway I can bring them back? This has never happened before and is only a problem with my latest published article, the previous articles still have their comments.

Kind regards,

Laura
