Hi,
Maybe senility is creeping in.
I thought I had paid for a Premium site, but I can find no record of having made a payment to Nabble's current Payment Provider, "Snipe". So I looked at the code for the forum in question and it includes the line of code:
<!-- Ad.true | 4032 credits -->
That indicates that I bought my credits under the old "Amazon Payments" system, sometime between October 2014 when the forum started and May 2015 when the new system came in.
That ties in with my memory of the origins of the forum.
As those credits haven't expired yet, I don't yet have a site with the new monthly subscription system, so can't help with the detail of how it works.
