  2. osman: this is very old i dont see this option under web server any help?

    • InterWorx: This option is available only on 6.0.x and 6.1.x. It also does not apply to servers running LiteSpeed as that is not compatible with our multiple PHP solution. If the multiple php option does not appear on the Webserver page, please submit a ticket to InterWorx support at with login credentials for the server and they will be happy to assist. Thanks!
