如果$ _POST不为空，则无法提交到页面

Question

I have a custom wordpress template page that acts as a login for a support area. I want the form to submit to the same page, the page is http:///supportarea. If I submit the form without any values I get the appropriate response from the page (or rather from my PHP functions) but the weird thing is if I submit it the same page with post values I get a 404 error.

Can anyone shed some light on this please?

UPDATE: If the form action points to the real location of the file it works but the url looks bad but doesn't seem to work on it's wordpress pretty URL with post values

action="/wp-content/themes/perceptive/supportarea/index.php"

Without form values:

With form values:

The response in FF:

Answer 1

Is any of your POST variables named "name"? Wordpress has weird bug that it gives 404 when there is variable "name" inside POST.
