I have just upgraded WP to 2.7. So while I was doing that I also upgraded the NextGen plugin.
Which all went smoothly. When I went back to my site all the images were gone. I figured out it was because the new nextgen gallery uses a different folder name. So I re-named it the same as it was before. All the images came back, but now I can not 'create' a new gallery in the NextGen admin. It simply wont save.
So now I dont know what to do! Any help would be greatly appreciated!
