Cannot switch php versions in 10.4.4

[trec]

I had updated from verison 10.0.0 to Parallels Plesk Panel 10.4.4 MU#22
Also installed PHP 5.3 update module so I could switch different php versions

After it I got PHP version 5.3.3 installed on all my sites
But I cannot switch the php versions on my domain names.

How can I update to PHP latests version 5.3.10 ?
How can I change php versions?
The "php version" select does not appear on the subscription webhosting configuration

Version:
OS Linux 2.6.18-194.32.1.el5
Panel version 10.4.4 Update #22, last updated at Mar 16, 2012 01:22 AM

The system is up-to-date; last checked at Mar 9, 2012 05:00 AM

Thanks

On Linux you cannot select PHP version per domain, it is only available in Windows version (simply because it is managed differently in Microsoft products).

Once you have desired version of PHP installed, it will be enabled for all sites. You can check the actual PHP version at Tools & Settings > Server Components
