/var/log/httpd/ssl_access_log
might be helpful, also if you are comfortable with bash and can read the scripts and understand what they do, in
/var/www/html/admin/modules
are a couple of shell scripts that are normally run from the GUI, for example to update all FreePBX modules on your system, (yum don't do that)
cd /var/www/html/admin/modules && ./import.sh
and
cd /var/www/html/admin/modules && ./update.sh
but be careful you should probably only be doing this on a broken system after you realized that you never made a functional backup
