Define the second site language, which will be used if the installed plugins don’t have translations for the first site language.
If the plugin does not have a translation file in a specific language, it will use the default translation (English). But in some cases it will be more useful to load another language other than English. This plugin allows to define this second language to be used when the first default language is not available.
Usage examples: 
– German formal (Sie) language by default and German (Du) language as second option. 
– Portuguese language by default and Spanish language as second option.

Second default language
