'Hide image' feature doesn't work

[charm]

Website http://zeno.ru, PP ver.5.62

When I click the 'Hide Image' link, nothing happens except for the words "Error on page" appearing in the bottom left corner of the browser window.

P.S. BTW, how this feature should work, if all is OK?

I show no issues testing this feature is an admin feature there is no way a site link is going to show me anything on your site. It works on my test site. Basically it is the ajax you click it and it will simply say hidden. You refresh your page or go back to the image you will see unhide image
