Hi
If I use any of the date type tokens in either listing or view html pages the articles module works as expected for host and all users. Any logged in roles return the following error.

I should mention that the tokens work in Print pages.
Also that I have an instance of the dnn events module that has been modified to start the week on Mon (europe) not the US's Sunday. 
The module displays according to date.
Interstingly: DNN Profile properties for this 3 times updated site allows the property to be deleted but this abilty was removed 4.5?
