Upgraded to 11.5 but now cannot login , redirect loop error, log says no fastcgi-5

[calmasacow2]

after updating to 11.5 it seems that most all of my services are running properly but I cant access the Plesk panel itself now. when I enter my login information and hit enter I get a "Redirect loop error" this happens in all browsers.

when I look in:
%plesk_dir%\admin\logs\php_error.log

I see a ton of :
[04-Oct-2013 13:27:58 America/Chicago] ERR (3) [panel]: Unable to create or update the subscription: The PHP handler "fastcgi-5" is not registered. It was probably deleted from the server. Register a handler with the same properties and try again.


Starting right after the install completed.

Have you tried repair Plesk with Reconfigurator? http://download1.parallels.com/Ples...dvanced-administration-guide/68471.htm#o49731
