Can’t edit link settings anymore

This is one site of several that are using Ribosome and have this same problem.
I add a link to a page… then attempt to edit the settings… or I try to edit the settings of an existing link… in both cases using the gear icon. The page immediately freezes.. so I can’t even scroll it anymore…

If I refresh the page, it restores and is just fine. All these sites are https sites by the way.. not sure if that matters or not. I only mention it because one site of mine using Ribosome http://HappinessNowHypnosis.com doesn’t seem to have the problem.

sure hope you can help me figure out what’s wrong and fix it. I like Ribosome and would hate to have to change Themes.
