My problem is very simple : to handle a GET request on my wordpress website I can type this : www.example.com/a-page/?thing=x But since the main is accessible via the root url (www.example.com/), if I type www.example.com/?thing=x it doesn't work.
I thought of forcing the website to display the homepage at www.example.com/home but I couldn't figure out how to do that. Plus I don't think it's really good for SEO.
