The invitation code is invalid

Hi! I'm using OM 1.3RC on Ubuntu 9.10. Everything seems to work fine, except when I send an invitation email about a planned meeting, when I click on the link in the mail, the page says 'The invitation code is invalid'. Any idea? Thanks in advance, Victorpictor -- You received this message
