ksingla:Can you try uninstalling CGI component and installing it again?
Thanks for the quick reply, that did the trick -- almost.
The module appeared in the list but then I ran into a 500 error: <handler> scriptProcessor could not be found in <fastCGI> application configuration.
Removing PHP and installing it again solved that. And btw, the default setting for date.timezone (empty) in php.ini may cause a warning on some installations, resulting again in a 500.
