Hi Daphne,
Firstly please open F12 developer tool and check what error it gives in console.
Due to many of Wordpress pages are php file, so have you embedded your form in a php file?
And as the tutorial you mentioned:
- check whether Wordpress has similar settings like "RemoveScript" in its folder or in GUI system settings
- any special characters in script are escaped by Wordpress
My suggestion:
You could create a plain .HTML web page without Wordpress control code(not in Wordpress .php files) and add a link on home page or any other page that navigate visitors to it.
I tested sucessfully in my own server, which home page is just a plain html file.
Regards,
Clofly
