PLEASE HELP really really stuck with shipping

OK I don't understand how any of the shipping modules work at all, and store owner breathing down my neck :no:

I had free shipping working for worldwide.

I needed freeshipping for all products domestically, and DHL prices on all products internationally.

OR

I needed flate rate worldwide on all products

I wasn't having much luck with the freeshipping so I turned of all my modules and turned on flat rate. I still got "Sorry, we are not shipping to your region at this time."

I set everything back to freeshipping everywhere (how I had it originally working), still: "Sorry, we are not shipping to your region at this time."

I have been asking this for sometime now and havn't been able to get a clear answer. I am dumb and need step by step in this I think....
SOMEONE PLEASE HELP!!

Hi Wolf,

try if it works by removing any zone restrictions you may have assigned to the shipping module. So it should be available to any customer from any country.
If you want to configure free shipping based on items/total you could clone the free shipping module to have two (separete by zones)

But...if your free shipping is defined by product "item is always free shipping", that might not work as you wish.
