I've made a custom page for the courses signup on CoursePress Pro, and have of course put in the shortcode to add the form -
However I am finding the form does not submit, and just reloads the page. There's no errors in the console, and even with WP debug mode turned on there are no errors. The user is not created in WordPress, so it looks like the form isn't submitting at all. If I use a virtual page, it works fine.
I've tried disabling plugins so that the site only uses essential ones, and also I've tried activating the default CoursePress theme without my customisations - but the error is still there. The only thing I can think of that could be connected is we changed the site URL. Could there be a reference to the old URL breaking the forms somehow?
