You have tried to use a one-time login link that has either been used...

You have tried to use a one-time login link that has either been used or is no longer valid. Please request a new one using the form below.

When requesting a new password, clicking on the link given in the email, this is the message the user gets even when done within a minute of requesting the new password.

Any idea what might be causing this?

Thanks.

:)
