A while back storiesonline.net (and their WLPC companion sites) changed their login system, changed everybody's theme/skin
and broke their theme/skin setting around the same time. See
#610
Since then, FFF changed to use the new login and they fixed the setting, although it was still changed for users, who need to go into their site account settings and change Listings Theme to 'Classic' for FFF to work.
However, it does look like I mistakenly removed the special case 404 handling that reported "
Story not found in Author's list--Set Access Level to Full Access and change Listings Theme back to Classic" to the user. I'll add that check back in.
