I am working with a 30+ site multi site setup (though I don't think multi site has anything to do with this question).
I have a form on my contact page that produces a "500 Internal Server" error message when the submit button is clicked.
The site is http but I think due to security settings here, this page has to be in https. I've tried the WordPress HTTPS plugin to no avail. Does anyone know what I need to do to make this page function in https and to change the links to https?
