@aeneasr fix for the broken pages in docs.
can you tell me why the build didn't succeed - it works locally

[aeneasr]

You should see it if you run npm run build - apparently a broken link somewhere

[vinckr]

Yea as I said the build works locally.

I get a lot of broken anchors but they are no issue.

[SUCCESS] Generated static files in "build".

I cant access the vercel logs so not sure what is the issue.

ok now this should revert any changes to the slugs/urls (+ a some small fixes)
