Why does Opencart give an error after installing the Yandex Maps script?

Question

Yandex maps

I created a map in Yandex and uploaded the script to opencart (in the footer), after which opencart gives an error.
I removed the map, returned everything as it was, cleared the cache in opencart, in chrome, nothing helps.
I can't find any other solution other than clearing the cache, please help.

Answer 1

Before doing this, you need to save a copy of the site. Somewhere they violated the syntax and so it remained.
find or download the same version and carefully replace the default/template/common/footer.twig file
