Question

opencart

I got a miracle on opencart. I started editing the article and stuck - it is now saved along with all the tags. Those. in the visual editor, tags and in the source, in general, some kind of mess. Accordingly, the output of the article is also a mess with html tags. Hence the question: what is broken and how to fix it? Opencart 2.3 Octstore

Answer 1

The Yandex map code is removed completely and other Yandex tags.

I solve it like this:
- In the visual editor, add something like {{map}}
- On the backend, replace {{map}} with the map code.
