Pagination bug on categories

[Marco Raaphorst]

When using /%category%/ in custom URL slug under Permalinks this creates links for posts using the categoryname in the URL. This creates a link like for example:
​https://domain.com/categoryname/blog-slug

This also means that ​https://domain.com/categoryname/ will show a page of all posts under that categoryname. But on this page, pagination is broken. Page 2, 3 or so on will cause a 404 error.

Hi @marco-raaphorst, thanks for making this ticket.

Can you provide more details? I am having trouble reproducing the issue that you are describing.

I did some searching and I think this report could be a duplicate of #37812. Can you review that ticket and confirm that is the same issue?

[Marco Raaphorst]

It's not the same as #37812. Although it is related.
Do this:

• set a custom permalink structure like this: /%category%/%postname%/
• now go to www.yourdomain/%category%/ and scroll down the page
• click on page 2, 3 or anything you'd like and you'll get a 404

Btw this bug is very very old, I think since version 1.0 :)

I also get 404 error when open subcategories links. This is odd, because when I click the subcategory link inside my weblog it works and shows subcategory items, But when I use the link from another website/bookmark/sitemap or Copy&Paste subcategory link in a new browser tab i face the same 404 error page!
I don't know if this is the same bug or not.
