Resourced Files Stopped Working Randomly

Up until about a month ago when a new player would join the server all the files I had resourced and on the web server would download to the client fine, now every player who joins and any new content I attempt to add results in a failure of resourced files to download to the client. I am befuddled as to why, the only notable thing I did was create a MyBB forums. If anyone has any ideas or simply a fragment of help, that would be greatly appreciated, thank you!

This also is happening on my other server and its web server, with no MyBB forums associated with it.
