Fatal Error moving Universal Email receipt from confirm.php page to checkout_success.php page

I would like to move the Universal Email receipt to the checkout_success.php page. This way if there's a problem with sending the email it won't affect processing the order. However, when I move it to the checkout_success page and change the trigger to before page load I get a fatal error. It says no such file, but the file is there. Any advice? And if I don't change the trigger but leave it to what it was, will the email still send properly (I'm only changing it because that's the method I've used in the past and eCart 6 is still new to me).

Warning: require_once(webassist/forms/persist.php): failed to open stream: No such file or directory in /Applications/MAMP/htdocs/CustomStickersforGoodCauses/webassist/email/templates/wa_receipt.php on line 1

Thanks!

I'll need to troubleshoot directly, see the private message section.

See PM.

New server site. See pm

i dont see the error you report on visiting the success page?

See pm

when the checkout form is submitted, it does an ajax call to load the confirm_cart.php and confirm pages.

It looks like you have applied your template to those pages, where it is using ajax to load those pages, they get loaded into the checkout page, you should not be applying the template to the confirm_cart or confirm pages, having the template on those pages is preventing them from loading correctly

see pm

just detaching the template should be fine.

edit the CSS that is attached to those pages to change the look and feel,
