[Plugin: NextGEN Gallery] Wrong paths after WP upgrade

I recently updated WP to 3.0. After the upgrade some image paths of my albums do not work and were not correct. The regular path looks like that:

http://www.angeltest.com/cms/?page_id=20

but when I swich to another images page (2, 3…)the path is wron with /cms/cms twice.

http://www.angeltest.com/cms/cms/?page_id=20&nggpage=2

It worked fine until the upgrade.

I am not an expert an probably made a green mistake.

cheers

Oliver
