HTTP 500 Internal Server Error after completed transaction (GoDaddy hosting)

It doesn't seem like a PayPal problem. Maybe a customization problem?

If you're getting "500" errors, then it seems you've got something amuck on your server that's triggering that, as kobra pointed out already this article should help point you in the right direction: https://www.zen-cart.com/tutorials/index.php?article=63

Does it possible that I've got the problem from Godaddy? If yes then I'll contact their support for this issue.

Answer: maybe.

Good luck with them!

But I better need your help before contact them, because they usually left me at least 12 hrs for 1 answer email.

Would you please give me more advise?

If you are getting a "500 Internal Server" error then the two most likely causes are:

1. Giving a PHP file permissions of 777 on a server which doesn't allow 777 permissions for PHP files. PHP files should have permissions of 644, except for the two configure.php files which would have permissions of 644, 444 or 400 depending on your server configuration. Check your files to see what permissions your PHP files have been given.

2. Something you have added to a htaccess file which causes the 500 error.
