[eluser]Unknown[/eluser]
Hello,

Routing problem:

Routes.php:

Code:

$route['krems/(.*)/(.*)'] = 'krems/search/$1/$2';
$route['ru/krems/(.*)/(.*)'] = 'ru/krems/search/$1/$2';

Htaccess

Code:

RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

Route .../krems/xx/xx - working just fine
Route .../ru/krems/xx/xx - not working

tried diferent ways, no success...
