Thanks for your reply. It appeared to be a re-direct issue and is now resolved, thanks.
I have now fixed the problem. I deleted the cache folder, renamed the plugins folder and then reset the URI
In certain cases your WordPress address URI may have been reset.
Check the siteurl value in the wp-options table of your WordPress database. A guide to doing this is available here.
Is it set as http:/?
If it is, change siteurl to the correct value.
