Hello to all, First of all, saddened for my approximate English, I'm french.... Here is: I do not manage to install CMS SUBRION on my server mutualized to 1&1 nor even on another server at OVH to this adress: http://coupon-a-imprimer.com/index.php . I have only errors 500. Nevertheless, here is my configuration to 1and1: PHP 5.5, MySQL 5 I tried to install(settle) Subrion in the root as well as in a directory / subrion / but nothing makes for it. I did not touch the .htaccess. Thank you for your help.
