When upgrading NagiosXI 5.4.9 -> NagiosXI 5.4.10 on CentOS 7.4.1708, I encountered a 500 error listing the following errors in /var/log/httpd/ssl_error_log:

I managed to get this working, but figured I'd share for anyone who runs into the same problem. Here's how I fixed the issue:

In the directory where I unpacked the nagiosxi installation tar.gz, I edited install-templates (this was the last file executed before the error occurred) from:

# Reconfigure Nagios
(
cd "$proddir/scripts"
./reconfigure_nagios.sh
)


TO:

# Reconfigure Nagios
(
cd "$proddir/scripts"
chmod -R 755 /usr/local/nagiosxi/html *
service httpd restart
./reconfigure_nagios.sh
)

Now, of course this is sub-optimal, but indeed it did let me get past the actual error. Hope this helps someone.

Thanks for sharing @krutaw! We will lookout for others affected by this.
