I have the Newsletter plugins installed on https://questforwisdom.org/ and want to give visitors of another website the possibility to subscribe to the newsletter. How can I do this?
Additional information: I created a subscribe form which generated code I could use on another site, however when I place this I get an error: We're sorry, but we could not fulfill your request for /?wpmlmethod=offsite&form=1 on this server.
