Hi,
Can you give more details about what you are trying and what is the error you are getting?
In Sendy > settings > response. Instead of a simple plain text response. I needed to add some html coding with additional features and info.
Your plugin works fine, it’s Contact Form 7. When they upgraded to V4.4. They’re not allowing HTML codes. http://contactform7.com/2016/01/27/html-is-not-allowed-in-messages/
You can by-pass this via using “class”, but I can’t seem to get it to work. I was on a deadline to launch the site, so I didn’t bother trying to figure it out.
Right now, I downgraded Contact Form back to V4.3.1 to allow HTML codes in the response
That shouldn’t create any problem.
You have to use the HTML in your form and CSS to show/hide the HTML
