Error with the Lightbox

Hi all,
I have an error with the lightbox. After I ping in a picture, the background turns into black and a layer with strange characters, like this :

is shown. The layer has a button to close it.
Checking the layer the div has the id=”fancybox-content”, and the source is the next:

<div id=”fancybox-content” style=”border-width: 10px; width: 1102px; height: auto;”>
<div style=”width:auto;height:auto;overflow: auto;position:relative;”>

The selected picture is shown in front of that layer, but if I close the normal picture, the layer with the strange chars remains.

Could someone help me, please? I want that the layer doesn’t be shown.

Thanks so much in advance
