Well, I don't know why it happens, but a workaround is to add a if statement to line 154:

if ($('.gallery-frame ul li',$el).length > 1) $('.gallery-slides', $el).append($slideButtons);

Hello,
I have the same error, and i don't know what to do.
Trying to apply the workaround, but i'm new in drupal so i don't know where can i apply this workaround. Please help.
I attached the image where you can see the green arrows before the colorbox.
How can i provide this? I don't know i just folow the steps that i saw in youtube :).

it's probably the css z-index property on the arrows, can you check with firebug the z-index of the overlay & of the arrows?

I'm closing it because the issue was created a long time ago without any further steps.

if you still need it then raise a new one.
thanks
