I keep getting 404 errors when logging into CPanel. Any ideas? My clients are having the same problem. Currently I have Cpanel 4.4.0-103. WHM works fine.
Are you using the full url? I get it occasionally when I forget to type http:// infront of the www.whatever.com:2082. Sticking the http:// back in fixes the problem.
Possibly not the problem for you, but sometimes it's the little things
