I'm using magento 2.0.7 , and yesterday my website start to have a strange issue , without any change. Basicly I have 2 payment gateway options , one is for cc and it works fine , the other one is paypal express checkout , and it was working fint till yesterday. Now , when I go on the checkout page , and press the "Pay with Paypal" button , I get an error saying:
You will be redirected to the PayPal website.
And if I press it while inspecting the page, I get this error:
jquery.js:9666 PUT https://xxxxxx.xx/rest/default/V1/guest-carts/c4f575f8d139addc9bc11795acaf25fe/selected-payment-method 501 (Method Not Implemented)
