Hi
I implemented the CMC extension and it works well.
However when a user registers through the module, I get the following error message:
400: xy@test.ch is already a list member. Use PUT to insert or update list members.
Below I get the message: Thank you! Please check your email and confirm the newsletter subscription.
The user (not already registered before) is registered anyway.
I'm using joomla 3.64 and the latest CMC extension 3.01.
Regards
Silvio
