Missing argument 2 for OAuthStoreSQL::getConsumer()

What steps will reproduce the problem?
1.Adjust links in templates to my use case (logon.php and register.php, instad 
of /logon and /register)
2.Run the provided example in /server/www/register.php

What is the expected output? What do you see instead?
It should echo the requester's key and secret instead I get:

Warning: Missing argument 2 for OAuthStoreSQL::getConsumer(), called in 
/xxx/xxx/xxx/www.example.com/oauth/example/server/www/register.php on line 14 
and defined in 
/xxx/xxx/xxx/www.example.com/oauth/library/store/OAuthStoreSQL.php on line 1111
Error: No access to the consumer information for consumer_key 
"89a596ae1017d82df3ac7d27a85e40fc04cab6c70"

What version of the product are you using? On what operating system?
oauth-php-155.tar.gz

Please provide any additional information below.
No wonder it is outputting an error: the function getConsumer() requires to be 
passed in the $user_id, which is not the case in the example.
