languages type switches to incorrect URL

[juliencarnot]

I have a LANG.md file with languages pointing to 'fr/' or 'en/', usign gitbook.com.

When using this option in books.json

		"versions": {
			"type": "languages"
		}

The dropdown appears with all the languages set in LANG.md, but when selecting another language, I go to https://www.gitbook.com/username.gitbooks.io/testmanual/content/fr/ instead of https://username.gitbooks.io/testmanual/content/fr/, and therefore have a 404 error
