Hi slash83;
I looked at your site, and it's not clear what the issue. is. Normally this is caused by a javascript error but I don't see any on your site. Can you try turning off all your other plugins and switching to the TwentyEleven theme to see if it's a plugin or them econflict? You can turn on your plugins one by one until you find the culprit. Once you find it, let me know and I'll see if it's something we can fix on our end.

Your case is a bit easier. I had a look at your site, and your theme or one of your plugins seems to be loading an old version of jQuery instead of using the version that comes bundled with WordPress.
It can create multiple conflicts with WordPress and with other plugins like Jetpack. You can read more about it here:

Try switching to a different theme for a few minutes, and check if that solves the issue; if it does, you'll want to look for the function loading jQuery in your theme's header.php file, or in the functions.php file. Once you find that function, you can remove it and enqueue the proper version of jQuery as explained here:

If the issue is not related to your theme, please try to disable all your plugins, one at a time, until you find the one that causes the conflict. You can then enqueue jQuery using the method I linked to above.
If you do not feel comfortable editing PHP files, you can also contact the theme or plugin author and ask them to solve the issue.
