Always 56 images

Hi, i’ve installed your pluggin, and I have to tell you thats amazing, but I have one problem: when I refresh my page the pluggin always show me the same number of photos, 56. It doesn’t matter the number I write in the limit shortcode, 99, 500 or 1000, the pluggin always is showing 56 random images from Twitter and Instagram.

I’ve tried reducing the thumbnails, but nothing.

The link of my page is http://www.joanteixido.com/2012/11/pintemcares/

Thanks a lot!
