[Solved] Error 403 for .php files

[Spheerys]

I have not .htaccess in the /htdocs directory and I changed manually the correct owner for all the files in the /htdocs directory

Is the problem can come from elsewhere ? (php configuration etc...) ? Because the index.htm file is OK from the web
But a simple php file with <?php echo "hello"; ?> makes a 403 error....

Very strange...
