In production we have a url /blog/articles/marketing-and-pr/ and when you hit the pagination for the first page it works as expected /blog/articles/marketing-and-pr/page/3/ but if you go forward again then it adds the next page to the end again /blog/articles/marketing-and-pr/page/3/page/4 and if you go back to page 2 then it is /blog/articles/marketing-and-pr/page/3// instead.
On my local development the pagination works correctly but not on production.
