Everything had been working fine until sometime today. Now when I invite a user they get the email and when they click the link to go to the registration page an error is generated.
The invitation <GUID> could not be found
I have looked in the event viewer on my SharePoint server and the only error that comes up immediately after inviting the user is the following
Source: ASP.NET 2.0.50727.0

Event ID: 1315

Any ideas or thoughts?
