Ruben,
These are the apparently gallery-related permissions in Permission Checks, which are all OK:
gallery/default/full (OK)
gallery/default/medium (OK)
gallery/default/thumbs (OK)
gallery/31/full (OK)
gallery/31/medium (OK)
gallery/31/thumbs (OK)
gallery/index.html/full (OK)
gallery/index.html/medium (OK)
gallery/index.html/thumbs (OK)
I resubmitted the forum permissions with a 1MB limit (1048576) on gallery images and attachments (and definitely selected the correct forum, not just the new forum template).
I have not modified Gallery Settings, but they look OK. The only mode available is GD2 (which is selected), thumb width is 125, med width is 450, full width is 1200, and the qualities are 6, 7, 8 respectively.
I'll try to debug the code a bit and see if I can figure out how the 0-byte limit is being arrived at, then (when I fail!) will probably open a ticket.
Thanks for your help!
