Description
After upgrading OS, the WebUI is blank and does not display anything, all PHP scripts are failing. Please assist me with getting things back up and running. Let me know what further information you require. Here are the errors that get returned when running some of the php scripts from cron, device rename / add for example.

Might have narrowed this down to a bad or old configuration parameter in the config.php file that breaks things. By removing it or commenting it out fixes all the posted errors and the web page and php script work. I have had this line in my config for more than 5 years and not sure why it's an issue now but I can reproduce the issue with it for what ever reason.
{ $config['ping'] = "/usr/sbin/ping"; }I suppose you may close this ticket.
Thank you,
