Gallery option – load more doesnt work

Hi,

I recognized, that the option load more or load by scrolling doesnt work for me.

Well, load by scrolling doesnt load the images and breaks the header, so I tried load more…you can try it on the link above, settings are images per page: 15 and images per load: 9.

If you click “Laden Sie mehr” it works once, but the second time it doesnt work and the footer isnt visible anymore.

Any suggestions to this?
