tracking NullReferenceExceptions in sitecore

Question

i\'m trying to track a NullReferenceException that shows up on sitecore 6.5 at loading any webpage:

[NullReferenceException: Object reference not set to an i         


        

Answer 1

I had similar problem and it turned out I had malformed config file. More specifically I must have pasted some random string at the beginning of the config file:

some_random_string

After removing redundant characters problem was solved.

However changing the name of problematic file also get rid of the exception.
