Error when accessing site settings

Hi,

I have created a site template from one of my existing sites in my SharePoint 2010 environment and used that site template to create another sub site from the root. When I click onSite Actions > Site Settings I get an unexpected error.

This is the only funny thing I could find in the log file and I'm not sure if it is related:

Does anyone have any idea as to what could be causing this kind of problem?

Any help would be appreciated

Thanks!
