The email I get after a backup is run contains the following WARNING:
Warnings : POTENTIAL PROBLEMS DETECTED; 1 warnings issued (see below).
You are using PHP 7.0.33 which is officially End of Life. We recommend using PHP 7.3 or later for best results. Your version of PHP, 7.0.33, will stop being supported by this backup software in the future.
However, when I interrogate the server via the hosting Control Panel or via the Joomla's menu "System"->"System Info", the PHP version is reported to be 7.3.3
Thanks.
Kind Regards,
AG
