Hi! I'm trying to install osTicket 1.9.2 on a CentOS 6 server running under VirtualBox to test whether it's a good fit for my organisation. I've reached a part in the installation that I can't get past - I'm getting a message saying: osTicket installer requires ability to write to the configuration file include/ost-config.phpNow, I followed the previous step and renamed the original sample file, I've also used to make it writable, but I'm still getting this error.Please help!
