Solution

  • It seems that you are trying to restore the backup on a newer server with a different configuration.

    PHP 5 as an ISAPI extension is actually PHP version 5.2, which is no longer supported by PHP community. It is recommended to modify the website code to make it compatible with newer PHP versions. The oldest supported PHP version at the moment is 5.6.

    If you still want to use PHP 5.2 ISAPI, you can add to any Plesk version except Plesk Onyx 17.8 in Tools & Settings > Updates & Upgrades or via a single line in CMD:

    C:\>"%plesk_bin%\ai.exe" --select-release-current --install-component php5
    

    As for smwebmail, you should have SmarterMail installed on the server and configured in Plesk. I suggest referring to Plesk documentation and help center for exact instructions, as it contains all necessary information. Here are some links:
