error 404 when customer fills out form and hits submit

are you using a plugin to generate the contact form?

I am trying to change that. I need to see how the submit button is set up. I can’t seem to get there. I jut want it to say thank you for submitting form. It is supposed to go to proper sales person and I don’t think it is doing that.

Your theme “singlesourcecom” is not to be found in the WP theme repo. You’ll be more likely to find a good answer from your theme’s support, for they have the access to its code.

This is how you have your form configured, the action pointing to:

https://www.singlesourcecom.com/wp-content/themes/singlesourcecom/contact_sub.php

<form method=”post” action=”https://www.singlesourcecom.com/wp-content/themes/singlesourcecom/contact_sub.php&#8221; name=”con_ff” onsubmit=”return con_check()”>

That page does not exist on your server. You should check where you want the page action to be sent to and make sure the page actually exists on your server.

The function con_check() does not exist on your original page either.
