~ # php -v

Web server

Make sure, that your installed files are owned by the user which runs the web server, especially if you installed as an other user!

Let's say, your document root is /var/www and the user is www-data (with group www-data) run the following command:

# chown -R www-data:www-data /var/www

Apache

For correct front end function, the following modules must be enabled:

• mod_rewrite
• mod_expires
• mod_headers
