Problem with TaigaChat

Hello
i have got TaigaChat Pro v1.4.3 and Xenforo version 1.5.9 , I cant post anything in the chat and i cant click any of the buttons in the shoutbox (js problem?)
anyone knows how to fix it?
thanks

You can see the problem pressing F12 in your browser.

Try a different browser

perhaps you have some broken html code somewhere else that is causing your buttons not to function correctly

link me your site if you want i will check it out, either here or in PM
