[support] I can't access my site!

[Daniel Carrera]

Hello,

I have moved a Drupal site to a new host and I can't access it! It gives 
me an access denied error and I believe that it is something with 
Drupal. Here is the site:

http://rosemarymusker.co.uk/index.php

I'm sure that it is a Drupal error because if you go to the update page 
you see this:

http://rosemarymusker.co.uk/update.php

You can see that this is a Drupal page, that Drupal itself is accessible 
and working but Drupal refuses to allow access. So the access denied 
error must be a problem with Drupal.

Does anyone have any suggestions?

Daniel.
