Small bug in pagination function paginate_links()

[kaderavek]

Hi,

we use on our site custom permalink structure - /%postname%-t%post_id% and we don't have / on end of url.

When we use function paginate_links for categories there are all urls ok except of first one - when you are e.g. there:
​https://mladypodnikatel.cz/akce-setkani/page/4
then all pagination links are ok (we add custom fragment but in not works if is without it too)
BUt the first link is with / in the end ​https://mladypodnikatel.cz/akce-setkani/ and this generate redirect which we don't want.

Can you fix it please?

Thanks

@kaderavek I'd love to help replicate this problem – could you post your template code so I could give it a shot?

Hello @kaderavek,

Welcome to WordPress Trac! Thanks for the ticket.

I'm sorry to hear you are having issues with your website. More information will help us to investigate and advise.

There are filters in the paginate_links function. It's possible a third party plugin or theme is filtering to cause the problem. Let's check.

• Please disable all plugins and switch to a default theme such as Twenty Twenty-One.
• Apply your template code.
• Does the issue still happen?

If yes, please provide us with your template code. Why? This will help us to reproduce the problem.

A few other housekeeping notes:

• Removing 5.6 as the Version. Why? 5.6 did not make functional changes to paginate_links function.
• Changing the Version to the function's initial version until we get more information.
• Removing needs-patch. Why? At this stage, we need to understand and reproduce the problem to determine if this is due to Core.

The bug is similar to #51662. I found it on 2 months ago. At first, we don't have this bug until one day we did SEO auditing again and found it.

[kaderavek]

Yes, its the same bug
