I am using WordPress to serve up a website, with the Exec-PHP to allow use of PHP code in the pages. I am trying to use the GET method and parameters to pass selection information to PHP code in the pages, to display varying information in the pages. An example is http://22.214.171.124/example/ in my website. When I look at the page with the above URL, the page is found. If I add "?m=2" to the end of the URL, I get a 404 error. Why would the addition of a GET parameter cause the page to "disappear".
