It looks like someone deleted your datacache table. Do you have a backup?
my what table?
probably not, no :/
gah, it's never been this much trouble installing this before >_>
if i do have a backup, where would it be and how would i put it back?
Did you just install your forum / do you have any data on it right now?
i installed it a couple of hours ago, just before work, however, i couldn't get past the table creation part, so i asked my friend who also works on the site to continue it from there.
i dunno were the data is :/
It's possible that the installation never finished, you should ask him to reinstall it again.
