[Plugin: NextGEN Gallery] Navigation problem

Hello,
My gallery has 48 images, the page initially shows 12 images, and when I click on page 1, 2 , 3, or 4, all I get is the loading icon, and then nothing happens. The same thing happens when I click on the ‘<‘ left and ‘>’ right buttons. The links are correct, if I right click on a navigation button and ‘open in a new tab’ then it navigates to the next 12 images fine (but in a new tab).

I also just discovered that if you quickly click the nav links while the page is loading then it WILL work. but when the page is fully loaded then it skrews up. any ideas why this would be happening?

see the page.
Anybody have this problem before?

I have also had a similar problem with the “like this post” plugin. I click ‘Like’ and I just get a loading rotating image and nothing happens. (its disabled at the moment)

I have the latest version of nextgen and wordpress at the time of this post.
