Only one method may be used to authenticate at a time (Auth header, GET or POST)

Trying to use WHMCS as an Open ID server with WordPress. Both running PHP 7.3.
But am getting this error when WHMCS redirects back to WordPress:
Only one method may be used to authenticate at a time (Auth header, GET or POST)Any ideas what could be wrong?
