Can't load Perl module ....

Hello again,

now I get the error above:

Can't load Perl module Apache::Ocsinventory::Plugins for server ... :0, exiting

and

...(you may need to install the Apache::Ocsinventory::Plugins::Officepack::Map module)

from /var/log/apache2/error.log

I don't know what causes the error. Before the error I moved some files so I think I had moved something at the wrong place. The solution here (http://ask.ocsinventory-ng.org/6630/cant-load-perl-module-apache-ocsinventory-plugins) wasn't successfull for me.

why isn't it possible to restart apache2 anymore?

Greetings
