Installing new language

I'll check again...

The file config.php should not be in those directories. It's the one in the forum root directory.

My question is; Should I edit the no_common.php file to reflect on the language settings? This is how the first lines are edited in the no_common.php file:

<?php

// Determine what locale to use
switch (PHP_OS)
{
    case 'WINNT':
    case 'WIN32':
        $locale = 'norwegian';
        break;

    case 'FreeBSD':
    case 'NetBSD':
    case 'OpenBSD':
        $locale = 'no_NO.ISO8859-1';
        break;

    default:
        $locale = 'no_NO';
        break;
}

// Attempt to set the locale (required for fulltext indexing to work correctly)
setlocale(LC_CTYPE, $locale);

// Language definitions for frequently used strings
$lang_common = array(

// Text orientation and encoding
'lang_direction'        =>    'LTR',    // LTR (Left-To-Right) or RTL (Right-To-Left)
'lang_encoding'            =>    'iso-8859-1',

I think I know what the problem could be; In the file no_common.php an apostrophe was not closed (\') - could this cause such problems?

If you mean single quotation marks were not closed i.e. instead of
'xxxx'
you had
'xxx
then that would do it. I did exactly the same thing when editing an English language file. It throws up an error because there is an unterminated string.

I deleted a closing quotation mark in en_common.php to make this line

'Delete posts'  =>  'Delete multiple posts,

(note the missing end quotation mark)

I uploaded the doctored file to my server. Now take a look
