Question: I know you have a contact form but if I have my own auto responder, how do you put it in the page or how will I get my emails with the current contact page?
Answer: You can use the "Text" block in the Page Builder and place it in the location you want it seen on the page layout. Place the autoresponder code there and it will be shown on WP pages that use your page layout.
Question: Why is the contact us Form not working?
Answer: The contact page will work if your web hosting allows php mails to be sent out using WordPress since the form uses WordPress' own mailing functions for that.
