1. The "Order" button works incorrectly, more precisely, when you click on the order button http://joxi.ru/L21MG1lfzJMgJ2, firstly, it does not throw anywhere, and just an order appears on top of the basket, but you still need to scroll to it.
2. The button "Leave a request" - after pressing again does not throw anywhere, it is unclickable http://joxi.ru/Vrw1zPnfjze812
3. The form on the contact page "Feedback" http://joxi.ru/l2Z0xJMTR3v7yr - after filling in all the fields and clicking on the "Send request" button, this http://joxi.ru/YmEL3QYtBWyBgr appears.
4. After going to the Cart, there is also a form "Ordering" http://joxi.ru/Y2LnQZ4CMg5xDr - and after you fill everything out and click on the order, this http://joxi.ru/MAjWBPJc1GQY8r
5. The form, when you go to any product http://joxi.ru/DrlLBYltGEgZWr, also does not work, because the button "Leave a request" does not work.
