By default PHP does not display error messages on screen. Some times you get a blank page when executing PHP scripts. Usually some sort of error has occurred, but this error text will not be displayed as SME Server is configured to not display them. Instead the error messages are reported to the log files of the webserver and the general logfile of the server.
Try to analyze your logfiles: /var/log/httpd/error_log and /var/log/httpd/access_log and perhaps also /var/log/messages.
If you (for debugging purposes for instance) would like to enable it you can do it with the instructions found below:
mkdir -p /etc/e-smith/templates-custom/etc/php.ini cp /etc/e-smith/templates/etc/php.ini/30ErrorHandling /etc/e-smith/templates-custom/etc/php.ini
After that:
cd /etc/e-smith/templates-custom/etc/php.ini pico 30ErrorHandling
Modify the second line to read:
display_errors = On
After that issue the following commands:
expand-template /etc/php.ini /etc/rc7.d/S86httpd-e-smith restart
Now access your page again and see what the error is. If everything works you remove the 30ErrorHandling file from the /etc/e-smith/templates-custom/etc/php.ini folder and issue the last two lines again:
expand-template /etc/php.ini /etc/rc7.d/S86httpd-e-smith restart
