Cheryl,

 
>>All i've done so far is add in the v5 files - so is there an extra property that i need to set to get around this?

No. There is no extrac property for this.

If you remove the example Cutesoft code from the Shared Common.config file, that should resolve the problems.

I think you still have some code in your page which links to outer site.  

Please double-check. I don't have any better idea now.

Keep me posted.
