404 error instead of created category on DLE site?

Question

CMS

I created a new category on the site similarly to the previous ones, but instead of a page with a category, a page with a 404 error appears on the transition, I tried to add something to the category - the page with the material is created and displayed, but the page of the category itself is still not there

Answer 1

there was a separate 404 page, removed it and everything worked
