Having problem loading the widget

I am no longer able to see the voting thumbs in my posts. I do however see loading ajax gif – only when i do display block in css via inspector, however nothing is being loaded otherwise. I got no errors, or any requests being made.

I am not sure what to do, besides uninstalling and installing it again.

It most definitely worked before! code is inserted in the loop, i mean i do see html markup and even loading gif, and database for posts is right, but the widget itself is just not showing up on the page.

Any suggestions perhaps?

Thank you in advance.
