This problem has been fixed as of 15th April 20:00 (uk time); I turned off SEF (Search Engine Friendly) url's in joomla global configuration....Don't know what has changed that required this setting to be turned off, all that has happened is FastCGI and PHP 5.2.13 has been installed.

Anyway Fixed....Yah!

The site is currently experiencing issues relating to site navigation and formatting of pages and this is being investigated.........

The site will be up and down for a while, as the the problems are looked into.

UPDATE: 15th April; I have now managed to get the server to serve pages again, however the navigation and formatting issues persist.

Hopefully have this back up and working soon, but things are taking longer than expected, who knows!

Sorry!
