Paytor disappeared, now part of Mollie?
According to the Wayback Machine Paytor still had it’s own website on August 14, 2018:

On December 27, 2018 the Wayback Machine captured a change, the Paytor website now redirects to the Mollie website:

Unfortunately we do not know exactly what happened to Paytor. We could not find any further information about this. Paytor is probably absorbed in Mollie.
