Previously it didn't support multisite properly and stored the info in the 'base database'. This was problematic since any of the sub-site can view the albums from other sub-sites.
I fixed this behavior in the latest version by separating the tables for each sub-sites.
Unfortunately this is creating a small problem for users who already had multisite setup with the previous version.
You need to do one of the following
Solution 1: Create the albums and galleries again under each sub-site (and delete the albums and galleries from the base site which was created for sub-sites)
Solution 2 (not recommended but quicker): Install the previous version (3.1.2)
On a multisite : Since the last update, the album list is available on one sub-site only. Every other sub-site Album lists are now empty (online we have an «Album not found» note showing).
How can we reassign each album to its sub-site or go back to the same list on each sub-site?
