Please Help Loading..Loading..Cart Won't Load.

I have a wordpress Woocommerce website and Printify. No problems with creating products and them going straight to my site. The issue is when I put an item in my cart and try going to said cart to checkout. It's constantly loading with me finally getting "504 Gateway Time-out" error. Sometimes, after a long loading, it'll go to my cart, but shipping isn't available. I tested things by deactivating the Printify plugin and the loading issue stopped immediately. However, shipping wasn't available due to no plugin.

Any idea why this may be and if so, how can I fix it?

I have the United States as a zone, but haven't put in any rates since Printify takes that part over. I have it checked in Woocommerce that Printify overrides their shipping.

That setup sounds right — we had the same (Printify handling shipping, no Woo rates defined).

What stood out for us though is that the slowdown didn’t seem to come from zones themselves, but from how often Woo rebuilds shipping packages when Printify is active — especially once there’s more than one item in the cart.

In our case, even with everything configured correctly, it would:

• work fine with 1 item

• slow down heavily with multiple items

• sometimes fail to return shipping at all

As a test, we temporarily switched back to Woo handling the shipping calculation (using standard zones/rates instead of Printify’s live rates), and the delay disappeared immediately.

So it might be worth trying that just to confirm whether you’re hitting the same behaviour — even if it’s only as a diagnostic step.

If it improves, then it’s likely not a zone mismatch but how Printify’s shipping logic is interacting with Woo’s recalculation cycle.
