We had some website downtime recently when sourceforge (the hosting company) moved datacenters. The move appeared to have changed the PHP version, and a single line in one of the php files was no longer valid syntax. wiiuse.net also uses the
Smarty template engine which requires some directories be set with certain permissions -- these directories had to be recreated as the datacenter move didn't copy everything. During the move, sourceforge disabled their shell account which I had been using for file management, and I was unaware until recently that sftp was available instead.
But, as you can see, we're back up and running now. Yay.
