Changes needed in Apache configuration for attachments to work in Helpdesk Pilot

With the new version of Ubuntu, Apache has also been upgraded and the FcgidMaxrequestLen directive needs to be included specifically in the hdp configuration file to support attaching files via ticket updates. To do this, 

1. Logged in as superuser, type cd /etc/apache2/sites-enabled
2. Type sudo nano instance-hdp
3. Go to the end of the file using the arrow keys and add the following before the last line (before </Virtualhost>)
   
   FcgidMaxRequestLen 10000000
4. Once this is added, press Ctrl+x followed by Y and press Enter to save the file.
5. Now reload apache with this command - sudo service apache2 reload

Once this is done, attachments will work fine on Helpdesk Pilot.
