I was trying to setup a multilingual joomla site, and Faroese wasn't an option so I asked this question: "Add Custom language to content language" but this didn't give the user the opportunity to select faroese in the language switcher, so I tried everything to get it to work, and ended with trying something stupid.
I downloaded the danish language package and changed everything that had da-DK to fo-FO file names and inside files. and made it into a new zip. It successfully installed the package. But when I choose Faroese to my site and administrator site it all went white. I tried to go into phpmyadmin and set the language to unpublished in xxxxx_languages table, this fixed the site. But administrator is still just white.
So where in the database is the setting for what language is being showed in administrator site so I can change it to something else?
