некоторые ссылки в плагине не работают.

When I click on any link it returns 404 Not Found, why?
In the vast majority of cases, this is caused by either one of those cases:

You do not have the .htaccess file uploaded.
Your web host provider does not have mod_rewrite enabled for Apache.
The .htaccess file exists, but the content is not the same as the original file from my product.

Получается, нуллили и сломали скрипт
