However it is not resolved for me.
Running the latest version 1.9.12; plugins disabled; permalinks activated and set to "post name"; deactivate gallery page link "unchecked".
All of my albums are displaying, however the galleries within the albums are not.
For example: My Ontario album has two galleries: http://www.bryan-crosby.ca/ontario/
When one clicks on these galleries they are merely redirected back to album, not to the list of thumbnails that is the gallery.
This is something I noticed recently when adding new photos after a long hiatus. I never had this problem prior.
