Hi,
You got it right.
The problem is caused by missing
tooltip() function. Your joomla template is calling the
tooltip() function without defining it.

I am seeing these 3 lines in your website source codes. But i don't know where those lines comes from (most likely from template's index.php or header PHP file)
What you need to do is, find the PHP file (look at your Joomla Template folder) that includes those 3 lines and remove those 3 lines.
Then, the TypeError will be gone and everything will work just fine.
Regards.
