Hello,

The two most common causes of this error are a corrupted .htaccess file and exceeding your server’s PHP memory limit. The .htaccess file in your WordPress directory can become corrupted after you install a plugin or make another change to your WordPress site.

The fix is simple. All you need to do is create a new .htaccess file.

Increasing Your PHP Memory Limit in WordPress
define(‘WP_MEMORY_LIMIT’, ‘128M’);

Thanks.

where do I set define(‘WP_MEMORY_LIMIT’, ‘128M’); ?

found it, in wp-config.

but it doesn’t work. checked htaccess, uploaded it again. and added that memory line to wp-config. still same issue

I found the bug.
This one is years old. Still not solved in WordPress!

I am using a category base. I am Dutch so I use categorie instead of category. AND I also use a custom URL structure: /%category%/%postname%/

This means that a URL to a post can look like this:
https://vervormer.nl/aflevering/advies-jaap-boots/

So https://vervormer.nl/aflevering/ will go to the category page BUT then pagenation is broken.

This is simply a bug. Using /%category%/ in custom URL slug causes this. It is allowed by WordPress but it is causing this bug.

Do I need to submit this bug to Trac?

Hello,

Happy to know that you found the bug.

I don’t think it is WP bug, but even though if you feel you can post that bug to Trac.

I would suggest to check once in fresh WP installation and try to replicate it.

Thanks.

Yes I can confirm it. With Heath Check enabled, no plugins running and default theme same issue occurs.

Will report this on Trac.
