I am interested in your script but the demo is in some other language which i am not able to understand. How come you do not have demo in English ?

When users try demo can set your language, so if account "user" set language french any users that try demo and use account "user" see interface in french language.
If you want change language you can:
- in user area from option (button)
- in admin/staff area from "Edit Profile" link (top-right)

If you prefer send us email and we reset language for you.

For further information email us.
