White board on Index but other sites works ok

Doesn't appear to be any way to uninstall a language in ACP, you would have to manually remove the language files, but don't think that would help.  Try reinstalling polish language pack in Admin -> Languages -> Add Language.

Having the same issue since I moved all the data to a new database.

A blank page if the user is not logged in.
It works if I go directly to a sub forum or to a topic.
It works if I am logged in.
It works if I disable that users can browse the forum (you are forced to log in or register).

I am using Norwegian UTF-8 as default language. If I change to English (and the users can choose language) it works.

Using .17.

So my workaround is now to have English as the default language and let the users choose language they want.

Have you tried running 'repair_settings.php.? It's possible the paths in the old database are not going where they should be

I was changing language to English and that's it. Trying to upload new language file do not help.

Thank You guys for all suggestions and help

First, make a copy of DB.

Set language to English and press button to convert all DB to UTF-8 - in my case I think there was a problem here
