I have been working on moving to a new server, and then to add a second server to improve performance. Currently, and temporarily, the replication is not perfect, which will, among some other minor things, prevent you from updating the card/miniature database. Please let me know if you need to do anything there and I’ll fix it for you.
Update: Ok, now you should be able to edit the database, but you may not see the results showing immediately on the site. I’m working on that now.
Update (Dec. 28th): Everything should be working again as usual.
