I have a client using WP 2.8 who is unable to sort galleries after upgrading to WP 2.8 from WP 2.7.1. I did upgrade the nextgen-gallery plugin to the latest version, but that did not fix the problem.
These are the steps I take to duplicate the issue:
1. Go into any gallery
2. Click "Sort Gallery"
3. Move a picture to a different position
4. Click "Update Sort Order"
5. After clicking "Update Sort Order" the page refreshes and the image is back in its prior position
I have the client set up with the NextGen FlashViewer plugin as well. I have tried updating Flash galleries and regular nextgen galleries, and neither will work.
The client has tried on two different Windows PCs and I have replicated the problem on my Linux box using Firefox.
I have also tried deactivating the Nextgen Flashviewer plugin and then sorting a regular nextgen gallery, but it still will not save the sorting.
Is anyone else experiencing this problem? Everything else about the plugin is working fine, the client just cannot sort images.
