Not sure if this is the right sub-board for this; please move it if it isn't.
I have an album that I created as an admin, and batch-added some pictures to it. Everything worked as it should.
I then created a group and user, and following the advice in this thread
I used the SQL statements for 'Adjust 1 album' and 'Adjust all pictures of 1 album' to change ownership to the new user. Checking in the database the owner_id for the gallery and it's pictures are now set to the new user.
When I then log in as the user, I can now edit the album, but if I go to edit files I get the message 'Album is empty'. I can go to the album and view the pictures as normal.
I added a single file to the album whilst logged in as the user, and I can now edit that one file but still not the original files. Comparing the entries in the pictures table in the database the original files and the new file appear to have all the same settings except the file path.
I checked the folder permissions as per the upload troubleshooting guide and they were all 755, so I changed them to 777 to eliminate that as a problem, but it made no difference (I have now changed them back to 755 as I don't like 777; too much of a security risk)
The whole use of Coppermine hinges on this. As the site webmaster I need to get the whole initial set up done with files uploaded before handing over to the individual users to carry on managing their own albums, but to achieve this I need to transfer ownership after uploading. I will also need to do the uploads on behalf of users sometimes, so again will need to change the ownership.
