I am see an error in the servers log file everytime I update a document’s details. PHP Strict Standards: Only variables should be passed by reference in /var/www/html/doc/edit.php on line 264, referer: http://myserver/doc/edit.php?id=147&state=3 It seems like the document details are saved though so I am not sure if I need to worry about this. I am using PHP Version 5.5.9-1 on Ubuntu linux 14.04
You can turn your log level down in your php.ini
error_reporting = E_ALL & ~E_DEPRECATED & ~E_NOTICE
