Hi Dax,
our site runs on Acymailing 6.18.3 and I try to run a subscription via URL as adviced in your post. I.e. with a link exactly like:
https://<domain>.de/index.php?option=com_acym&ctrl=frontusers&task=subscribe&hiddenlists=1&user[email]=<my>%40<email>.de
Unfortunately i don't get it work.
The browser gives me an message that says:
"Das Abonnement ist auf eingeloggte Benutzer beschränkt."
(in English: "The subscription is limited to logged in users.")
Any idea whats wrong?
BR, SRN
Edit:
I just found the issue.
"Allow non-logged in users:" must be activated in the subscriptions settings.
