Sanity check

These checks failed:

• [statistics] Statistics dir [/var/log/simplesamlphp/stats/] is not writable

These checks succeeded:

• [core] Password in config.php is set properly
• [core] In config.php technicalcontact_email is set properly
• [core] You are running a PHP version suitable for SimpleSAMLphp.
• [sanitycheck] At least the sanity check itself is working :)
• [statistics] Statistics dir [/var/log/simplesamlphp/stats/] exists
• [statistics] Input file [/var/log/simplesamlphp.stat] exists
