this is probably due to the database becoming corrupted yesterday and being restored from a backup.

i doubt you'll get them back, obviously that depends on the extent of the corruption to the database and how kind the admins are feeling

Yes, unfortunately the database became corrupted, and DaniWeb was down for nearly 12 hours, resulting in me not sleeping at all and having to play hooky to one of my courses yesterday to catch up on some zzzzs (I couldn't even keep my eyes open trying to get ready to leave so driving to school and sitting through class was out of the question!).
