Customize option for subscription editing is missing in the Plesk interface.
Since Plesk 18.0.39 right sidebar is collapsed and as a consequence Customize option is hidden.
- Log into Plesk.
- Navigate to Subscriptions > example.com page and expand right sidebar menu by pressing the button:
Make the sidebar expanded by default for all clients:
Connect to the server via SSH
- Open the panel.ini editor:
# plesk conf panel.ini
- Add the next section in there:
collapseSecondarySidebar = false
- Update the settings for the currently registered clients using the next command:
# plesk db "update cl_param set val='false' where param='collapsedSecondarySidebar'"
