I am trying to do an email subscriber form and I would like to implement my own solution. I do not want to spend hours trying to figure out which Plugins is the best. Spending more times to install it in the template. And then realize that I can't easily send back a confirmation email to the subscriber... All I want is a normal .php file and do my job real fast inside.
Let's call that page sign-up.php
But, if I POST (even if I only GET) on that page, my 404.php is being displayed. How can I avoid this? I could probably go edit my .htaccess but I do not know if WP is going to overwrite it to get rid of my instructions.
I am using WP 3.4.1
