You're not looking at an Apache problem, but a PHP problem. 500 is the error code for a failed CGI script/program. Try executing the php from the command line. i.e. Go to where ever /services/portal/sidebar.php is and execute: ./sidebar.php httpclient=1 See what, if any, errors are thrown that way. PHP is notorious for not sending good errors into the logs or to STDERR.
