I need to add a Mailchimp form popup to my current Wordpress website. I only want this pop-up to appear on a specific page. The code I currently have does not appear to be working. I have read a couple of workarounds - one is creating a new [login to view URL] file and uploading this to the root directory of the website to trick it. This did not work. I found another copy and paste set of code in Github - this also did not work. I am not a technical person (can do the basics) so don't know the in's and out's of where paste to paste the code and any other potential plugins or other issues which may be blocking the pop-up.
