Undefined index: user_lang in /var/www/cpg/include/init.inc.php on line 203

I get the following error on the very top when I login:

Code Select Expand

Undefined index: user_lang in /var/www/cpg/include/init.inc.php on line 203

line 203 looks like this:

Code Select Expand

        define('USER_GROUP_SET', '(' . $USER_DATA['group_id'] . ($USER_DATA['user_lang'] != '' ? ',' . $USER_DATA['user_lang'] : '') . ')');

What does that exactly mean and how can I fix it? Didnt find anything when I used the search.

Looks like you're running an old version of init.inc.php. Verify using the versioncheck.php

Got that right ... uploaded the actual file and everything works fine.
Thanks.
