Forum Problems with UTF-8 conversion
 

I have problems with my vBulletin forum since I upgraded to vBulletin 4.0.2 from 3.8.x.

The language settings are correct and uses UTF-8 but the rest of the forums, the threads and forum names and descriptions and so on are showing ? instead of swedish characters.

The database and all tables are converted to UTF-8.
I think the problem is that character_set_database is UTF-8 and character_set_connection is latin1. I tried to follow this guide but it fails.
As soon as I change the value of $config['Mysqli']['charset'] to 'utf8'; or sets $config['Mysqli']['ini_file'] to point out the ini file I get the following warnings and gets logged out:

Warning: array_keys() [function.array-keys]: The first argument should be an array in [path]/includes/functions.php on line 5194

Warning: Invalid argument supplied for foreach() in [path]/includes/functions.php on line 5194

Any ideas what to do?

Im using Mysql version: 5.0.67 and PHP Version 5.2.6.



My settings in config.php
$config['Database']['dbtype'] = 'mysqli';
$config['Mysqli']['charset'] = 'utf8';
$config['Mysqli']['ini_file'] = '/home/g/gtiklubb/www/forumx/mysqli.ini';

SHOW VARIABLES LIKE 'char%'
character_set_client latin1
character_set_connection latin1
character_set_database utf8
character_set_filesystem binary
character_set_results latin1
character_set_server latin1
character_set_system utf8
