url issue on category slugs

[ersinkurtdal]

This url structure is used to split the posts of a category into pages.

.../category/{category_name}/page/2/

However, if you use /0 before the /page/2/ section, the system ignores /0 and it does not redirect to the 404 page and opens the /page/2 archive page. But in this page, the single_cat_title() function does not return a value.

.../category/{category_name}/0/page/2/

Even all parameters entered before /0 are ignored too

.../category/{category_name}/1/2/3/4/5/abc/0/page/2/
