I would like to thank the Otrs team and all the members of the group for responding back.
 
Today i raised a question about the shortest way of upgrading from 2.4.4 to 2.4.5.
 
I did it by manually downloading the source code (the zip file of 2.4.5)
 
Stopping the apache server from services
 
getting backup of the otrs\otrs folder only
 
replace the new files 2.4.5
 
After that the apache did not start..
 
What i did was to restore the following files back to where they were :
 
20.10.2009  23:05    <DIR>          Apache
14.07.2005  02:46            16.061 apache-httpd.conf
16.04.2007  15:11               962 apache-httpd.include.conf
01.10.2009  08:59             7.469 apache-perl-startup.pl
01.10.2009  09:01             4.633 Apache.pm
20.10.2009  23:05    <DIR>          Apache2
01.10.2009  08:59             1.410 apache2-httpd-new.include.conf
16.04.2007  15:11             1.249 apache2-httpd.include.conf
01.10.2009  08:59             7.542 apache2-perl-startup.pl
 
Then started it up.
 
It worked..  Plus i had the problem of notification events not sent to customers issue.
 
That's solved too.
 
Thanks & Regards
