I recently installed version 4.8.04 of Dotnetnuke and after the third day of working on it, I'm getting the following errors:

 "A Critical Error has occurred. Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.Net request."

I've also seen the following error (using the IE browser):

A critical error has occurred.
Validation of v13wstat3 MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

 

What exactly do these errors mean?  How can I resolve them?

most of the time it is sufficient to restart application, i.e. by opening and saving web.config file. Issue can be cause by an offending 3rd party module or IIS configuration, e.g. server side compression.

The errors starting showing up after uploading a couple of modules.  I installed a few 3rd party modules like BTBRandomImage, Weather, DNNStuff Google Analytics.  How can I tell which one is the culprit?
