tooltip doesn't work anymore

Hi,

I saw that the tooltips doesn’t work anymore, I don’t know since when.

On console I see errors like:

Error: TypeError: jQuery(…).tooltip is not a function
Source File: http://miratico.ro/cele-mai-inalte-cruci-din-lume-pana-la-ceruri/
Line: 409

I hope you can do something about it.

Thank you,
Lucian
