Changes to php.ini not taking effect
I modified my php.ini file to change a PHP setting, but the changes didn't take effect. Why won't it work?
Centova Cast v3 does not use your PHP installation, so accordingly, it does not use your php.ini file.
Centova Cast v3 contains its own self-contained PHP engine that is completely independent of any other PHP installation on your server. You can, in fact, completely uninstall PHP from your server (if nothing else on the server is using it) and Centova Cast will continue operating normally.
