What else is not working? You are using a lot of plugins and a commercial theme (those are not supported here) so you'll need to start sorting out what may be causing any problems. Generally, start by deactivating plugins to see if any are causing problems. If not, leave them off and switch to a default theme - test again. If it's the theme, ask the developers of the theme. If a plugin, post on that plugins own forum.
That said, you can also check for JS errors and other errors:
