[TYPO3-english] [sr_feuser_register] Links to activation without ID

[Robert Jędruszek]

I installed the extension Frontend User Registration 
(sr_feuser_register) and configured in accordance with the 
documentation, especially the chapter Configuration steps. Then I 
created a structure of pages, register user, and then I received an 
email to confirm registration. Unfortunately, I can't confirm the 
registration, because the registration links come without any 
identification string - I get only the link in the format 
http://domain.com/.

Does anybody know why activation links in mail come incomplete?
