Troubleshooting Multi-Carrier Shipping Plugin for WooCommerce
Enable Debug Mode
The first step towards finding a solution is to enable the Debug mode in the plugin settings, as shown in the screenshot below.
Once you enable this setting, you can view the request and response information on cart and checkout page. If a customer has entered an invalid destination address, selected a service/package that is not available in that region, and other related issues can be viewed in these sections.
Following is a sample screenshot of request and response data, when debug mode is enabled.
If the problem still persists…
If debugging shipping method doesn’t solve the problem, consider the below case.
The issues stated earlier can also occur when you have a shared hosting service, which makes difficult to understand the root cause of the problem.
In such cases, the solution is simple. In your MySQL configuration file, increase the value of max_allowed_packet. Usually, in a shared hosting service, this value is set less. You can increase this value accordingly. The recommended value is max_allowed_packet=16M.
