Lately, I upgraded by Wordpress website to version 4.6.1 and I not sure if that caused issue or something else, but my site is no longer able to filter out posts on the basis of categories.

When I visit my category archive page using www.mysite.com/category/some-category, it shows 404 page. Though I am able to assign categories to post, but apart from not being able to filter on categories in the front-end, when I filter using dropdown in the All Post (in wp-admin/edit.php), I get a blank list eventhough I have post assigned to those categories.

Not sure if this has something to do with .htaccess rewrite or SEO plugin as suggested in posts but I've tries tweaking these up with no success.

    if you don't include any code that might be messing with categories and permalinks we here cannot offer anything but wild guesses.

  • Sorry, I have no all seeing eye which allows me to scan the harddisk of your server to see which themes and plugins you have installed.

  • @cjbj, I really did not mean to ask you to scan the servers hard disk. I was just trying to ask from where should I post the code (if its the .htaccess, plugin, archive.php... etc). I am aware of the Stack Overflow "asking question best practices" and I am also aware that I should post codes as well, but a wordpress installation has over thousand files and if I had any Idea where to look for, I would not had asked such a dumb question here. Sorry and I am not trying to be offensive. But thats the fact.

  • What are your settings under Settings -> Permalinks? Apr 14, 2017 at 7:21

Quite often, after WP or plugin updates, just re-saving the Settings->Permalinks works for me (without changing anything).
