Modal Links Error: "Something gone wrong here…"

Hey, there.

I just downloaded Modal Links and set a window to open from clicking an image in certain page. I’m using the shortcode:

[modalLinks permalink=”pessoa-01″]<img class=”alignnone wp-image-190 size-medium” src=”http://www.ufrgs.br/intervires/wp-content/uploads/2014/05/the-poet-correct-1-240×183.jpg&#8221; alt=”the-poet-correct-1″ width=”240″ height=”183″ />[/modalLinks]

This is the page where the modal should open (clicking the first image, right under “Sobre Nós”): http://www.ufrgs.br/intervires/v-de-intervires-teste.

The link seems right, that is, when you mouse over the image it shows the right path to open, and indeed it opens if I type it manually in a new window, but it won’t open as modal… No matter what I do, I always get this error: http://www.ufrgs.br/intervires/wp-content/uploads/2014/06/modal-error.jpg.

Any ideas on what may be going on?

Thank you in advance.
