Anyone good at diagnosing scripts for authorize.net

Hello everyone, I mostly deal with creating custom scripts so on. I have a client that asked if I could take a look at their auth.net script that is giving them an error.

Here is what was said in the email as well as the error. I need someone that can do this for a quick $50 OBO.


I switched from shared hosting to grid hosting and now my authorize.net transactions show this error message:

"Your script timed out while we were trying to post transaction results to
it.
Transaction ID: 0
Transaction Result: This transaction has been approved.

The following message was displayed to the customer:

------------------------------An error occurred while trying to report
this transaction to the merchant. An e-mail has been sent to the merchant
informing them of the error. The following is the result of the attempt to
charge your credit card.

This transaction has been approved."

tried set_time_limit(0) at the begining?

here some info with same problem
