I have tried launching sites on fresh installs of ISPConfig 3 on two different servers. Both servers seen to work fine, ISPConfig 3 seems to function fine, and I have tried various nameservers, all of which point to either of the two servers. If I run a reverse traceroute, dns lookup, etc, every different setting resolved perfectly every time. They are both wordpress sites which I have installed my fair share of times. The connection strings from MySql to wp-config are perfect too. Each time, same error....500 internal server error. PS, the monitor on both set-ups is all green...all systems go? Thanks.
