I have been using Mailpoet for over a year now and after the last upgrade it seems not to want to connect to server and has an issue sending emails.
I get this error code
“An error has happened while performing a request, the server has responded with response code 0”
And “auto save will not save as a unsubcribe link has to be in the footer” however I have done this a number of tims and it still will not progress.
