Hello !
I apologize, someone offered to take care of this site and did not actually do it and the website has been inactive for a year.
I still plan on keeping it alive but the launch of my company in between has made me quite busy.
I have no idea why subscription does not work anymore as I didn’t touch anything. Either the softr subscription that kept it alive ran out, or there was a softr update that broke it.
I am glad there is a solution in the forum but since I see there is still traffic every day coming to my site, new registrations, and people subscribing to softr through it, I will not abandon the project.
