Description

When you try to go from a page on vuejs.org to ua.vuejs.org and pt.vuejs.org, like this one - https://vuejs.org/guide/essentials/application.html, you'll run into an error. I only noticed this in the docs section. It only works if you didn't change pages before trying to switch to the UA/PT version.

The same problem has it.vuejs.org, an error section appears.
