Hi support,
Unnder category pages, in the pagination section, the link going back to the first page of the category contain and extra slash at the end which cause a 301 redirect.
Note: this extra slash in URL affect only the link going back to the first page of the category.
e.g.
/category/news/ <— the problem here
/category/news/page/2
/category/news/page/3
/category/news/page/4
/category/news/page/5
