502579 Fix my vbullein Website Error

Hey guys, now that I`m opening my vbulletin forum website, it`s giving this error: On firefox: Content Encoding Error The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression. On Safari: Safari can't open the page “[login to view URL]”. The error is: “cannot decode raw data” (NSURLErrorDomain:-1015) Please choose Safari > Report Bugs to Apple, note the error number, and describe what you did before you saw this message. Please note that`s it`s a very small site and suddenly it`s giving me this error. Wan`t it fixed asap.
