Common Queries: Plesk FAQs, Part 8

a) What is the “Phusion Passenger Server” that can be installed on Plesk for Linux ?

The Phusion Passenger server enables Ruby and Django web applications on Plesk servers, with installation via the Plesk installer in Plesk 12.5, but configuration and deployment must be done manually.

b) If I upgrade to Plesk 12.5, will Web Presence Builder (WPB) be removed from my server ?

Web Presence Builder remains functional and enables customers to edit and publish their sites as before the upgrade. In Plesk 12.5, it becomes an optional component, allowing users to uninstall it from the server using the Plesk installer interface (Tools & Settings > Updates & Upgrades).

c) Can I upgrade to Plesk 12.5 and ensure CBM functionality if I currently use Plesk 12.0 with clients and business managers ?

Upgrade to Plesk 12.5 and CBM will continue to function, as they are integrated using the Plesk XML-RPC API, which supports multiple versions and offers extensive backward compatibility.

d) What is a “permanent ban” in fail2ban ?

A permanent ban is an internet term referring to an indefinite ban on a user by fail2ban.

e) Do virtual server licenses have to be installed in a virtualized environment ?

Virtual server licenses are exclusively for virtual servers, so it’s crucial to check the requirements for supported virtualization solutions before purchasing, as Plesk may not recognize the environment as virtualized.
