We have a subscription free of charge and paid memberships (gateway Paypal und offline payment).

The email process for the free subscription works fine.
The email- and payment process with Paypal works fine.

But the offline payment email process didn´t work. I get the final payment landing page but the mails with the payment instructions and the register emails (mail adress confirmation and welcome mail) did not sent. Is there a problem with the email sequence?



At the bottom is a red bar, looks like a error message without text. Don´t know if this is relevant.

Any ideas what blocks the email processing for offline payment?
The global system mailing, uddeim or acymailing works fine. So I think it´s a CB Subs setting.
