Hello,
I've got a wordpress instalation with acymailing on one side, on the other side I've got another custom website with a form. What i want to do is that people who fill that form and check the 'newsletter checkbox' are added to the acymailing list created in wordpress.
I've been reading the documentation:
https://docs.acymailing.com/developers/acymailing-developer-documentation
And i have loaded the Wordpress API okey, but when loading acymailing libraries i've got a 500 error.
I'm stuck in this.
