Was this resolved? I'm on Archon 3.21, I saw this thread so attempted to upgrade to Archon 3.21-r1 without success. (I copied the codebase to my file system, overwrote the config file with my 3.21, overwrote the /themes/ and /files/ directories with my 3.21, pulled up Archon in my browser, and got a big WARNING that everything in my DB would be lost if I proceeded. Not really successful at finding specific Upgrade instructions -- there are plenty of Installation instructions, but Upgrade, not so much....)
We are trying to dump the contents of our Archon out into EAD for, er, archival purposes! Not having much luck.
Any and all advice appreciated,
