I have Plesk 8.2.0 installed on my Linux RHEL4. Version of PHP ws 4.3.9 and I tried to install php5 via Linux command line. I needed PHP5 because I wanted to install last version of MediaWiki and it needed PHP5. I successfully installed PHP5 by compiling and building it from its source package and Plesk identified it. Now when I want to use Plesk Updater to update my Plesk components, it fails and gives an error that means it has problem with PHP5 and needs PHP 4.3.9. What must I do?
