If CMSimple produces error messages when validating your page, what can you do?

The text of the message: 'cannot generate system identifier for general entity “PHPSESSID”'

means, that a string like &PHPSESSID= somestringhere3432423 is added to all links in your page.

This is caused by PHP Sessionhandling which is used by some plugins, for example AdvancedNews Version 1.0.0

The & in that string is validated as an error, & are expected as & to be correct

what can be done?

1. these settings can be changed in the php.ini: The separator used in PHP generated URLs to separate arguments: Default is ”&”. set it to arg_separator.output = ”&”

1. if you cannot modify the php.ini (for sure not possible at most hosting services) you can try to set a flag in the .htaccess file: add php_value arg_separator.output & to your .htaccess file

1. if you cannot modify or add .htaccess-files to your webspace do this:

• identify the script which starts sessions, find session_start();
• add this line before session_start(); : ini_set('arg_separator.output', '&');
