XF 2.2 Requesting password error "Oops! We ran into some problems".


Many users are reporting issues when signing up on our forum.

After registration, using Steam Auth we re-direct them to the password reset page to get a password (required for our application).
When they press the reset button and get the email, opening the email link sometimes results in the following error message.

"Oops! We ran into some problems.
Your action could not be confirmed. Please request a new confirmation."

Any ideas?
Been a right pain for many months now.
