Background
A "No response from store" error message is generated when using a custom script for integrating with the Order Manager.
Cause
The customer entered the wrong URL in the Order Manager's Shopping Cart Setup.
The customer entered incorrect login credentials and the script is not passing back an appropriate error.
The script was written and tested using "GET" whereas the Order Manager uses a "POST" when making the request which is causing an error when the script runs.
Some other error is occurring causing the script to fail before outputting data.
Solution
Contact Stone Edge Technologies Tech Support with the shopping cart's URL and the user's login credentials so the script can be tested.
