No probs Jass, I still have not resolved the issue, however I am sure the problem lies within one of the following:
:arrow: Hardware Router Firewall (One Device - Netgear DG814)
:arrow: The DNS Settings
:arrow: Or Incorrect / error of installation upon Apache.
If anyone else reads this post with any suggestions, please let me know as it is piculiar!
Many Thanks
George.
PS: Jass, no I dont have to type http://localhost/tester.php as I have routed the httpd.conf file to another location on the local pc, but I dont think this would affect the error in anyway!
