opencart .htaccess redirect subfolder to subdomain language not working

hi i install opencart in subfolder web8.us/shop/ and redirected
permanently to shop.web8.us in .htaccess like
RewriteEngine On Options +FollowSymLinks RewriteBase /
RewriteCond %{http_host} ^web8.us [nc] RewriteRule ^(.*)$
http://www.web8.us/$1 [L,R=301]
this is the magic line below here
RedirectMatch 301 ^/shop/(.*)$ http://shop.web8.us/$1
all work good whit out languages if you like to change language from
english to spanish its stackon english any ideas?
thank you in advance GEORGI
