Error on marker after update

I just updated the component to latest version and in our global map with marker i don't see anymore the map but only text with marker as in the screenshot attached.
You can see the page online here: www.lifeintravel.it/tutti-i-percorsi-mtb-di-lifeintravel.html

Can you please advice me what kind of error can be?

Hi
Sorry for delay, I didn't get email about new post.

Check your page source, I can show little code below

 

As you can see lines 1405 - 1407
Some HTML injection in my code

It is not mine, and it breaks all

Thanks for your support,
you pointed me in the right direction... it was some code inserted by a plugin i 'm using.

Now it's solved!
