Url and page content are different. How to fix?

Question

Joomla

Hello.
I have a question. There is a site. Every month I check it for duplicates through Yandex Webmaster.
Recently, the webmaster shows their availability, for example,
https://website/boots
https://website/shoes
When you click on "shoes", a page with "boots" opens. All the content is from the page with boots, but for some reason shoes are urd.
It seems to me that the problem is in htaccess, tk. there are many redirects. There are also suspicions of viruses or some kind of extension.
Please tell me what it could be and how to fix it?

Answer 1

I thought for a long time that it could be, but, in general, I will answer this way)
Maybe htaccess, because. there might be a lot of redirects.
There are also suspicions of viruses, why not.
Although there may be some extension.
Without some additional information, it is impossible to answer what the hell is going on there.
You need to see the same htaccess, the site itself, the list of installed junk.
Although, most likely you need a deeper dive, access and so on.
Naturally, not for free, on some freelance exchange.
