Hi Robert,

Since ujpdating wpforo, I can no longer edit topics.  This is very problematic for me as administrator.  My site is jeannemayell.com/community/

You have JS error on your website.

Here is the error:

ReferenceError: stLight is not defined

This error affects wpForo front-end buttons. Here are the list of discussions about this. Some of them says this is a ShareThis feature/plugin. I'd recommend disable other plugins and enable them one by one.
