The script does not have a valid include (match) rules

[IRainman]

I have a big problem with this script (same for Google Extra buttons). The script broke the other sites. I don't want to publish URL here because currently this is XSS, which allows me to create a order without paying. Currently I work with support of the site so that they fix the vulnerability on their site.

You need to set correct include list for ya.ru, yandex.ru, yandex.com etc.
