Verification problem

In need of a little help!

 

I am trying to get my site http://www.danwisepat.co.uk/ verified, and have been using the method of uploading a HTML authentication file to my root folder (using Filezilla). I can see that I have uploaded the file to the root menu (and not in a sub section) but am getting no joy. Attempting to visit the confirmation page just leads to a page with a message that there has been an error. Any advice would be greatly appreciated!

 

Cheers.
