Object reference not set to an instance of an object.

How frustrating!

So I have set up my tree structure. On each page I had two properties, a "header" (textstring) and "bodyText (ElasticTextbox from uComponents). They were on a document type that every other page inherited from.

I then deleted these two properties, and added a whole bunch more to a specific document type and saved it.

Now I am getting the same error on every page when I try to access it from the "Content":

Server Error in '/' Application.

Object reference not set to an instance of an object.

Anyone have any ideas? I"ve tried adding the properties back and and I've stopped using ElasticTextBox anywhere...

Thanks in advance.

All good. I've got it working. First, I backed my DB up (for good measure), then went around deleting properties off pages, eventually I removed the offending one, then I had to add them back in, being careful to avoid items that came with uComponents. It seemed to work.

Quite time consuming and annoying though...
