Fundraisers with manual payment error

Hi,
I must did something wrong. I try to set up Fundraisers for donation on the website http://event.thaisahajayoga.com/blog/fundraisers/donate/

I need to have manual payment for our users, not everyone prefer PayPal. I set everything in the Settings to receive Manual Payment. Put the Information displayed after pledging. But when I test it (link above), it always return to Page Not Found. Please tell me where I have to look or set to fix this.

My web is Multisite and have Event Espresso installed.

Thank you,

Kaiwan
