404 Error

OK, so… I’ve made some new discoverings. The 404 error happens when a specific Slug QTS is used. For example before I installed QTS I had a page with abc as url. Later, I changed it to abc-def. After I’ve installed QTS I defined abc as Slug QTS and I receive the 404 error… But then, if I set a new Slug QTS, let’s say xyz everything works well.
It seams the old posts names doesn’t work. Any ideas about it?

Hi Luís,

Yesterday I looked at your website and noticed that it was working, so i forgot to reply here.

if I understood right, when you set the new slug to the same as the old one, you get a 404?

Let me test on my testing wp.

Hi Pedro,

I had a url set as https://www.luiscosta.info/mooc and now https://www.luiscosta.info/pt/mooc/ and https://www.luiscosta.info/en/mooc/ gives me a 404 error (if I change it to https://www.luiscosta.info/pt/mooc123/ it will work)

I also had a url set to https://www.luiscosta.info/tecnologia-social/ and now https://www.luiscosta.info/pt/tecnologia-social/ gives me a 404 error but https://www.luiscosta.info/en/social-technology/ is properly working

Hi Pedro and Luís.
I Have the exactly same problem. When I edit any old post, It gives me a 404 error… If I Change the permalink so the url, the 404 is fixed. The problem is that i don′t want to change the post url…

hi everyone, i found in a site of mine that there was collisions in the slugs. For example, i had a custom post type, that had “slug-1” and a normal post “slug-1”.

changing one of them fixed that issue. i also tested against attachments, and found that there’s a possibility that it collides with the slugs.

if you have access to phpmyadmin, search for the slug in the post table in “post_name”.

i’m working to fix this as soon as possible.

Hi there,

We have the same problem with the 404 errors. It would be great to have a fix.

Thank you Pedro for your work.

Hi Pedro,

Do you have any news about this problem?

Thanks a lot for your work and support!
