Background of the issue:
I am trying to access certain pages on my website, but I encounter a 404 error. The problematic URLs are: hidden link and hidden link. The same pages are accessible with lowercase URLs: hidden link and hidden link. I have not created any redirects for the first set of pages.
Symptoms:
When I try to access the pages with capital letters in the URL, I get a 404 error.
Questions:
Where these pages with capital letters in the URL comes from?
Why do I get a 404 error when accessing pages with capital letters in the URL?
How can I resolve the issue of 404 errors for URLs with capital letters?
I cannot say why you are seeing those URLs in the Google Search Console, as those URLs don't exist on your site. Perhaps there's an option to re-index your pages.
As a suggestion, you can also try searching for the "category" slug and checking its translations in WPML → String Translation in case of an error in the slug translation.
