To find out what went wrong you need to turn off the custom errors mode.
1. Open web.config file
2. Find out the following line <customErrors defaultRedirect="errorpage.htm" mode="RemoteOnly">
3. Replace it with <customErrors defaultRedirect="errorpage.htm" mode="Off">

PLEASE REMOVE. A solution was found.

I have had a site running on NOP for a couple years with very few issues.   However, today an issue occurred when trying to view or add a product to the cart.

Here is the error stack.

Thanks!

I also had the same problem but it was only when I clicked on two different categories.  Since I am still in Set-up mode I deleted the categories and then added them back with the same products.  This fixed the problem for now, but I am concerned that this will happen again since I don't really know what caused it in the first place.
