We just switched hosts and encountered an error I just can't figure out. Help would really be appreciated.

Upon order completion the success page is "Page Not Found". We are using only linkpoint and gift certificates. The problem occurs when using either which leads me to believe it's not a linkpoint configuration issue. I enabled logging and get nothing in the log. I was sure it was a php error somewhere due to something I changed. I also thought it might be SSL but if I turn SSL off the same error occurs.

So...

https://www.urbanobaby.com/index.php...eckout_process

shows "Page not found".

The order completes, an email confirmation is sent, and it shows in the admin. Its just the redirect to the success page.

However, when you go directly to the success page it shows accurately for the last order and the remaining gift value.

I changed a lot on the site in the last week and we are on a new host (bluehost), which makes me unsure of when the error began occuring. However, I did not change anything in the process header files...

Any help would be much appreciated, I am stumped.
