Hello again..
One question this time.
In Administrator/General/History are site's stats.

In table, field "stats_file" has value: category, picture, search etc.
In which file I can find this value (want to translate them), they arent in /languge/.

PS I found one error in "element_set.php"
Value:
  $page['title'] = 'caddie';

should be change to:
  $page['title'] = $lang['Caddie'];

only them 'Caddie' will be translate to proper language :)
