I've just bought and installed send. I is a perfect solution, I loved. Your start guide is the clearest! I do some test (only words), and it worked perfect. But when I try to paste my html code and save it, I get an error
"(406) Not Acceptable An appropriate representation of the requested resource /sendy/includes/create/save-campaign.php could not be found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."
Thank you in advance for the time!
