"Please select a Shipping Method!" msg at checkout

I've added product, category and unpublished all shipping methods except "free shipping" and set the free shipping threshold to 1. At checkout however, the shopper cannot get pass the "delivery method" step. What am I missing?

Hello,
What did you enter for Min sub total and Geo zone in the configuration of Free Shipping? Can you also take a screenshot and put it here?
Sincerely, Giang

I used "all zones" and threshold quantity is set to "1"

Now it displays the shipping option but it still displays the same error message —even after selecting the free shipping method.

So I was successful in getting one order to go through successfully. All other attempts display same message as above. I've tried Safari, Chrome and Firefox for Mac OS. I've cleared browser cache but the same message remains.

If it's helpful, here's a link .

Hi again breeze,
Thank you for giving me these information. All is correct. This was a small bug in older version of EShop. I think that you are not using the latest version. Can you please download the latest version 1.2.5 and updated it on your site then test again?
I am sure that it will be resolved.
Hope to hear back from you soon.
Sincerely, Giang

Thanks. I didn't realized my installed version was outdated. It works fine now. Thanks for the great customer support.

That is no problem!
If you need any more helps any time, please don't hesitate to let me know.
Sincerely, Giang
