Umbraco 5: Security Exception

Installing umbraco

I have uploaded the files to the server (shared hosting from Winhost) - but when accessing the site I get the below error. Any idea what is wrong?

Security Exception

I solved the problem by setting <trust level="Full"/> in web.config

Peter, glad you got it working, though running in a full trust environment really wouldn't be my recommendation.

The U5 has a permissions checker as part of the installation which can be invoked by manually browsing to the path where it resides - I don't have a U5 instance here right now to check, but if you rummage around under the 'Install' directories (just do a search for those if needs be) you should be able to locate it. I'm not even entirely sure what it will tell you if your permissions fail (or, 'when', considering we know they're wrong when not in full trust), but it should hopefully give some useful indication as to what exactly is restricted, meaning you can ammend the permissions for that object directly based on the requirements of such.
