Hello,
After investigation i have successfully installed Prestashop in your ngayvu account in box3.
Shop URL: Prestashop
Admin URL: http://ngayvui.clubos.net/prestashop/admin746/
Login details: check your PM.
You haven't seen next button in the first step probably due to Counter Code. I have Removed The Counter Code by placing .htaccess file in domain ngayvui.clubos.net public_html directory with the following line:
Code:
php_value auto_append_file none
Second problem was files and folders permissions. I was not been able to proceed to the third step while permissions was 755. After setting them to 777, installation proceeded to next step.
Also, if you will want to remove this installation and make new install, i have placed fresh files in the file manager prestashop directory.
