Thanks for respond for me...
Anyway, I feel that I am very very very beginner for doing that...
I tried to change a language in virtue mart , but I couldn't... The reason is that I didn't find any language access in virtue mart even after entering product detail information area...
I found how to change it in virtue mart and I knew it:
administrator/components/com_virtuemart/languages.
Unfortunately, the "com_virtuemart" is not in my admin area...
First off all, I need to change language of product in virtue mart, then have to change default language of Joomla, isn't it?
Please explain it very in detail and write a way clearly...
Thanks...
