Mysterious errors from dotText (.Text)

For years — pretty much since I started my blog — I’ve been getting emails from people saying that they get an error from my blog engine (.Text aka dottext). 

Value cannot be null. Parameter name: value

Usually, by the time I get there to check it’s working fine.  Somehow it fixes itself.  Today…not so much. 

Fortunately, I found a blog post on this error with The Solution.  (Thanks to K. Scott Allen.)
