Requested URL/forum3/content/main/htm was not found on ....

[SnyperBunny]

I keep getting a blank white page with an error on it "the requested URL /forum3/content/main.htm was not found on this server."
This is happening when trying to flip to the second page of a forum search, from links that come up on a google search (both on my phone and comp), as well as when actually clicking a result in a forum search. If I take the "#postnumber" (eg #p179355) off the end of the link then the thread will come up though.

This is also listed on the page: "Apache/2.2.3 (CentOS) Server at www.applesnail.net Port 80"

I have had similar glitches just over the past few days
