I was using Virtualbox version of Bitnami PhpBB stack version 3.2.8-0,
And today I noticed that all the forums, threads and posts are gone from the forum. All content has reverted to the original state of the forum. Except for the name of the admin account. All other users are gone as well, and the admin password has changed from the password I specified, so I can't even access the admin control panel.
