As an agreement with hsaleh the condition should be `more than 1` instead of `more than 0`.

Here is the logic condition:

• If the site has not any language set then of course the languages nav won't be rendered.
• If the site has at least 1 language already set then the languages nav won't be rendered.
• If the site has at least 2 or more languages already set then the languages nav will be rendered.
