Hello,
I use JS 4.7.1 and i have problem with static text 'Shipping description'. I have edited this in Configuration -> Static text. I have also checked 'Show Plus shipping' in Category/Product configuratoin. There is link to that static in frontend but it directs to blank page with 500 error:
Link to produckt page:
