I’ve made a sort of archive website for my older blogposts. I divided them up into categories. But now the categories don’t show, it’s just an empty page. See for instance: https://www.mediawijsmetmuriel.nl/category/mediawijsheid-vo/ Whereby if you go to the blogposts directly, everything is fine. For instance https://www.mediawijsmetmuriel.nl/website-maken-om-mediawijs-te-worden/ Is there a bug? Or can I do something to fix this?
I guess you’re trying to say either you did not get categories link in post or category page is empty. But while checking your site, I did not get any of such issues. Can you explain more clearly if there’s still an issue.
This might be caused by plugins you’re using. So, you can try deactivating plugins one by one and check if your issue resolves. Also, if you’ve changed any theme’s file, please revert back. If it still persists, please let us know again.
