I read that some users have been receiving this error when trying to login to sites such as (but not limited to) naughtydog.com, killzone.com, myresistance.net etc.
If you receive the error when attempting to login: "Missing return URL parameter." The simple fix is to allow third party cookies on your browser. Most people suggested using another browser, it wasn't the browser that's the problem, it's that third party cookies are blocked. Login requires third party cookies to be enabled. If third party cookies are blocked/disabled, you will receive this error and will not be able to login.
