Thanks for help The link enabled to available exists, The second is required just for user directory ( I have same problem even if I put the file in /var/www ) , any way the lines are commented.
I installed phpmyadmin it works fine, so the php runs correctly, so I need probably to modify somewhere a config file. I suspect that something is new, because I used ( 2 or 3 of years ago) it exactly in the same way. thanks a lot
