JSON Error

Hello, I can no longer login to my WHM as I am getting this error: (XID p9fapg) The system failed to parse the JSON stream data "" for the caller "(eval)" because of an error: malformed JSON string, neither tag, array, object, number, string or atom, at character offset 0 (before "(end of string)") at /usr/local/cpanel/Cpanel/JSON.pm line 123. at /usr/local/cpanel/Cpanel/LicenseAuthn.pm line 37.

Do you know what has caused this from the error above? Regards, Ben
