I have a bit of a strange discovery after copying my phpbb installation to a new domain. It appears that forum posts are somehow reading and writing to its previous database even though the config file has been updated to its new database. I am guessing that the database connection is cached somehow, and the cache has been copied over from the previous install.
After copying the site over, we removed all of the forums and posts. The site has been copied several times without anybody noticing this happening. So now we have 3 installations (possibly 4) that are all effecting whatever the original installation is/was.
It's a pretty nifty clusterf*#&% for sure.
I am trying to figure out the original installation so it can be restored from a backup.
Does anyone know where in the cache this would be stored? or even some useful strings to search for in the cache that could lead me to the original source database config?
