Error after installing YML OpenCart module?

Question

opencart

Guys, such a disaster, I installed the YML export module, and now the "Promotion channels" page is no longer displayed. It says page not found. I have version 2.0.3.0. The module itself was installed, but in the Modules / Modifiers tab, near the yandex module, it says "Converted to 2.3.0.2". I understand that the error is due to different versions of the module and the site?
