There is a problem with attachments in old spoilers. I've checked mine and they all are gone. Not sure how to correct this. Will manually changing them to url and civduelzone from civ3duelzone help? Were they actually there recently?
They were there at the time the forum was moved. Do you still have them on a backup? If you can put them with original names for some upload folder, can they be recovered at new domain? Since they just worked fine form the old domain, and you left the old CDZ online, there were no problems with that. IIRC, the attachment database could not be converted and it did not. It shows me having like 20 of total attachments while is should be over a couple of hundred.
