Transfer my order page to a new page

I need to get my order page transfer to a new page as the url keeps getting an error. I need it fixed right away. My website was built in Wix and menus and order page are with Wix Restaurant, I don’t want to use the Wix Restaurant feature for now as there’s something wrong with their app. Please visit https://www.appleliciouscatering.com/online-ordering
and you will see the error page. This is just a one page so budget is $20 CAD.
