Hi, 

I'm getting 404 errors from the submit POST request when submitting event RSVPs .  At first I was worried it was my theme I was working on, but even when using a default nationbuilder theme I'm getting errors the same errors. 

URL (ignore how ugly this page is, it is WIP): http://act.mayday.us/press_conference_with_zephyr_teachout

Any advice?  Browser error is below.
