see if you could help me, with the same issue with Piwigo, I'm trying to change the storage location of the images, because I have a hard drive with the Ubuntu Server OS with all the Apache, MySQL and then I have 2 disks that make a RAID, and the RAID is where I have more space, I'm modifying it so that it points to the RAID folder, but it creates the folders on the main disk. Thank you very much.
