My language switcher does not work only from the blog page

Question

I've written my language switcher as below.

It works from / or from /blog/<blog-post> but it does not work from the /blog page even if /en/blog is available.

<a href="{{ '.'|url(alt='jp') }}">Japanese</a> | <a href="{{ '.'|url(alt='en') }}"> English </a>

Is it bug or should I fix something?

Below is my web site language switcher is available on top-right of the page.

• Working (top level page): http://www.socoka.com/
• Not working (Blog page): http://www.socoka.com/blog/

Answer 1

In Lektor versions < 2 there are some limitations with regards to the alts. This is working correctly in Lektor 2 which is currently in development only. But you can install it from the git master if you already want to use it.

Answer 2

It can be reproduced by adding the following patch to quickstart project (project name: alt_test)

Tested environment is below.

lektor version: bc61976a0c7aca3374a40d55f633a83e0686c247
