I know that I had the same problem in another website but i've chaecked everything and the translation doesn't works.
The website is www.danceontheworld.com
The main language of this website is "english"
I've checked on the plugin and module which main language is selected, it's english.
SEF options is ok: Use URL rewriting
I choose "Redirect" method
I didn't add the google API Key
The backend and frantend are in english
I can't find what is wrong... gtranslate doesn't translate...
thanks for your support.
