I’ve figured out the trouble and I’m hoping there’s a workaround. We have two Printful stores, from two different designers, stocking our WooCommerce store. The Printful Shipping API is for one of those stores only. Is there anyway to allow both stores to be integrated through the Printful shipping plugin?
I’m going through this same thing. It actually worked once right after I set up the Printful shipping integration but has never worked again. I deleted wordpress transient cache by going to Woocommerce>Status>Tools>clear transients with no change. Followed other advice to enable/disable WooCommerce shipping, have disabled/enabled “Use HTTP instead of HTTPS to connect to the Printful API” Deactivated Braintree, set up zones and then deleted them.
I’m tired of this. What am I doing wrong?
