css not working in local server 0_o?

Question

linux

In short, the essence is this, put LAMP on ubuntu all the cases, threw in the site template. When you try to change the styles in the style.css file or when you delete them, everything remains in place, but if you change the styles in the index.php itself, then everything works out. The same is true with style.css and index.html when simply viewing the document in a browser.
In general, the situation is such that on a local site, a site with all styles is visible, but it is IMPOSSIBLE to change them, specifically through a linked css file.
With what it can be connected 0_o?
Thanks in advance :)
The problem is solved, it turns out it's all because of the tag<base href="">
