UPgraded from 9.3 to 11 and now Plesk CP won't work

[SCMG_IAN]

We recently had a website breach and some injected code so asked Fasthosts about nay possible causes. They mentioned a problem Plesk had encountered so suggested we upgrade Plesk CP 9.3 to 11

The processes run by us to resolve a recent breach of Plesk are as follws to make it easy to follow:

We ran the automated installers for Plesk CP and was going from 9.3 to 11

We received the success screen.

Then found that no sites would run or the Plesk control panels

NOTE: we use "IIS mod rewrite" on our 2 servers

What we noticed was that the Application Pools for Plesk had stopped. You could start them but when you then tried to access a website the Plesk App Pool would be Stopped.

We managed to get our sites back up and running by creating an Application Pool that was not the same one Plesk uses and we atached all our sites to it so the sites now work fine and the IIS mod rewrite rules are all working just fine.

Problem we still have is Plesk CP won’t load


Any ideas?????
