I have the most current version of NextGen Gallery, 1.9.3, and the most current WordPress. I loaded in some galleries last fall and they sorted perfectly. Upgraded the plug in tonight as it was the first time in a while I had logged in (yeah, I'm slow on updates and posting. Working on that). Loaded in a new gallery, and the sort is not working at all. I have checked Gallery Options and they are set to custom. I have turned off all of the other plugins (only 4 others activated) and no change. I've tried all of the various sort options, and none of them change anything. I can only guess that this is a version clash but don't know for sure.
New gallery is not viewable right now though I can change that if need be. Blog address is http://photomonk.com
