The forum displays have now been fixed, thanks to Motrucker's bug report.
For some unknown reason, each forum was set to ONLY display threads from the last day, sorted by thread title, Ascending (alphabetically). I don't know whether that happened on the initial import, or whether one of the module installations changed it without me noticing, but each forum has been changed to;
Show threads from the last 30 days;
Sort by last post time;
Descending
This should be much more akin to the way Xoops displayed forums. PLEASE NOTE that if you posted in the last few days, your post has NOT been deleted, it merely wasn't being displayed properly. It should now be correct.
This is one of the main reasons I needed the "
bug report page", and I do sincerely appreciate the help in finding these things, as I'm just one guy with failing eyesight and a short attention span.
