Links Disappear in my Post

When I am creating a post and try to add a link once I save or publish my post the links disappear. Blank spots are left where the link should be. I’ve tried deactivating all my Plug ins, the only one that was activated was the JetPack plug in, but that didn’t help. How do I fix this problem? I had to take the post down because it doesn’t make sense without the links I’m trying to add in. It’s very frustrating.
