I Can't see buttons of Image Show GK4

Hi, I've another problem with image Show GK4.
Some time ago I've removed the link of buttons of the slide, and the buttons are disappear.
Now I need to insert again buttons, but also I insert the url in module's settings, I can't see any button.

This is the site: http://www.alimamedia.com/
And this is a screen of module's settings: http://www.hybridupload.com/14/06/7b5z.png

Hello,

If you have applied some modifications in the module code, then the only way to revert it is comparing the modified files with the original ones.

where I can find them?

You can download the module from our download area.

Now it works, thanks!
