I have installed PrestaShop 1.7.6.3 to Ubuntu nginx server. Everything works fine with a lot of modules added.
The problem is with the first button "Add to Cart and Continue Shopping" - it fails, with message "An error occurred while processing your request".
If I click second button "Add to cart and continue to the checkout" - it works.
I can't find the reason of the error anywhere - development mode is ON, no message in PrestaShop Log, no message in Nginx Log...
Same project on Apache server on localhost works well.
What to do?
