Chat plug in: error: "$(this).closest is not a function"


I get the following error when activating the chat plug-in on my website:

“$(this).closest is not a function”

I got this error from firebug.

The chat is looking very weird in both firefox and chrome.

Please help me make the chat work on my site.

    Hiya Daniel,

    I’m not seeing that error when I visit the site myself.

    To help troubleshoot the cause, can you try the following please?;

    – disable all plugins

    – revert to the default theme

    – check whether the issue persists

    If the error goes away that tells us that another plugin, or your theme is causing the error. Re-activate each one at a time to find out which one it is.
