Hi, a site is throwing the above error on the contact page and:
Property accessor 'CategoriesTreeView' on object 'Telerik.Cms.Engine.WebControls.Categories.CategoriesTree' threw the following exception:'The type initializer for 'Telerik.Framework.Web.ControlUtils' threw an exception.'
on another page.
When loggin into the admin the same error as the title appears:
[ArgumentException: An item with the same key has already been added.]
The site has not changed form last night when I edited some blog templates and was working fine afterwards. I also changed the Telerik.Sitefinity.Configuration.ControlsConfig.xml by adding a new template. I upoaded the original file before incase that was the error.
I am a very new Sitefinity user and the site is hosted on a shared server (Server2003, HSphere CP, ASP.NET 3.5 and Sitefinity 3.6.1936.3)
