Next & Previous button not working on Chrome

Hello,

The next and previous button are not working on Chrome and Safari although there are working on Firefox (and when using the keyboard).
When clicked, it just closes the slider.

Here is an example:

Do you have any idea what causes the problem?

Beside this, the plugin is really one of the best gallery plugin i’ve seen so far so congrats and thank you!

Cheers
