We have Plesk ‘WordPress Toolkit Free’ version installed. It does not allow us to select “Donot not install any updates” without upgrading the Toolkit subscription. And Moreover the WordPress in question does not show up in Plesk control panel. (It was installed outside of Plesk using the duplicator plugin and not installed via Plesk Control Panel).
It’s actually a chart which is converted from word file to html. Tried with Mammoth but only problem is that it do not maintain color and indentation.
