Odd question

[Daedroth]

I run a website, that I hardly ever use, it's to a game that I no longer play, but I keep the site up for the members of the faction I was in. Anyway today I received an "HTTP 404 - Page Not Found" error on every page.  I updated all the pages on the FTP server and that made the site work well, except the ACP.  Now when I click go to ACP on my phpbb forum i get the "HTTP 404 - Page Not Found" any clue what that is and how to fix it? The page is there, I just uploaded it again.

Be sure you have the proper URL defined within your phpbb options.
