Cannot see any logs in Magento 2 instance connected to this error.

There is similar problem that is connected to current behavior - shipping methods are not loaded and default "DPD Courier" id displayed. After returning to non-checkout page and proceeding to Checkout - default shipping method is replaced with methods from Magento.

Local environment:

"directBackendSync": true in VS and "useServerQueue": false in API

Hey @kovinka , yesterday we've updated master branch with 1.7 release. I cannot replicate your case. Could you check if it's still an issue for you?

[kovinka]

@patzick, cannot check, looks like some problems on https://demo.vuestorefront.io/, cleared all caches, but cannot open any page

[patzick]

Looks definitely like cache problem, because current files hash is 9e0d450bd6af8bbf9528

Could you try again? Please go to Application -> Clear storage -> Clear site data and run Ctrl+f5/CMD+r

[kovinka]

@patzick, done, also tried to open in incognito mode, hash is correct

Clicking on "Place the order" does nothing on orderReview step after placing the order before and adding new product and trying to checkout again (pls don't change payment method on 2nd attempt and use 'Check / Money order' method for payment), after reloading the page - button can be clicked (i think because of PR #2133), @patzick could you please check it and after that i can try to reproduce it again

@kovinka is this still a case?

[kovinka]

@pkarw
as for checkout - yes, the "Place order" button still does nothing for 2nd checkout process.
Steps:

• add item, proceed to checkout, choose "Check/money order", place order
• don't reload the page, return to any product, add it to cart, proceed to checkout, don't switch between payment methods (Check/money order should be selected) and try to place order - no action.

as for "error while placing order" - will check again, it reproduces not every time.

@patzick it would be great to check this before Wednesday

@kovinka thanks, you're right. #2505 will solve this problem
