After update to 2.0.77.3 white screen at Gallery Settings and Other Options

Hi Cais,
After updating to 2.0.77.3 I get a white screen at the Gallery settings page and the Other Options page.
Because of that my photos aren’t opening in a lightbox anymore.
I have 4 sites and 3 of them work alright after the update.
One of those 3 sites even has the same theme as the 4th site with the problems.
I already deactivated Nextgen and activated it again, but that didn’t help.
You can see the photos here, at the bottom of the page: http://www.patriciakaas.nl/blog/
What can I do?
