Shipping method not showing at checkout page.

I have an opencart store (http://simeqtechnologies.com/mimelon) with latest version 3.0.2.0.
I have enabled the "Weight Based Shipping" and enabled the shipping method for all Geo Zones.
Still it is not showing at checkout page.
Please anyone helpw me to solved it out..

have you configured the various geo zones rates?

Take a look at my help topic here:

My guess is that it has to do with product weight classes or your default weight class. Double-check all of those.
