I am having the same issue
@rrlrcwebmngr – Are you seeing any error messages, or have you checked for conflicts with other active plugins?
– Cais.
no error messages drag gallery to album but gallery just slides back to original position
@rrlrcwebmngr – I have only seen similar behavior if there is no album selected.
Under Gallery > Manage Albums … choose an album from the drop-down selector (wait a moment, or two), and the panel will change to allow you to modify the album, including being able to drag-n-drop galleries (and other albums) into it.
If you are doing this and still not able to add your galleries to the album of your choice, please submit a Bug Report (http://www.nextgen-gallery.com/report-bug/ … please reference this topic) so we can get a closer look at what might be going on.
We will need log in and FTP credentials for your WordPress installation, please include those in the Bug Report.
Thanks!
