I started getting this error on the checkout page of my site:There were problems getting a shipping quote.
the calculate shipping button also disappeared, and the shipping is not being calculated.
The products setting is set correctly to small packages.
I didn't find any errors in the reports/recent log entries.
tried to disable jquery update but it didn't help.
I use a flat rate free shipping in the US and $5 international, and I made sure that the conditional action is set correctly.
