Warning: choose shipping method!! Weird issue....

Hi there,

I am having issues with the shipping modules.

My situation:


I have serval ''free shipping'' duplications! Each district in POSTNL have it owns prices based on weight shipping.
And if you reach an amount like 20, 50, 60 euros you will recieve free shipping. Thats oke! But when you want to go further to payments! I get this in the delivery methods: Warning: Shipping method required!

how to fix this

Hi,

Any developer need check files to understand what can cause this problems;

If your custom shipping extension is not created based on opencart rules then no one can figure out where is problem without to check files;
