hello, I made the standard intallation for joomla in French
1) Pack creation of a module of French contents
2) New menu welcome and module associated menu
3) Validation of the language manadger
Furthermore sj_cars_templates_j17-j25_v1.2 of this template does not install ! Only the version full Quick install in transfer FTP is OK
virtuemart is ok and the other module native joomla are ok in french ...
your module register/login is half in french half in english
If you have the solution I is given to you my access admin, I shall just love the menu Register login, and the contact in French ...
I am not a pro, but I have of the installed about fifty templates and I have never met this kind of problem which makes waste a lot of time, damage, if this template cannot parameters in French it is enough to indicate it ...
