HgLab was working great for me until today. I tried to do a post and the client (SourceTree) gets this: HTTP Error 500: Object reference not set to an instance of an object.

I looked in event viewer on the server and found this:
    Exception type: HttpException
    Exception message: Server cannot modify cookies after HTTP headers have been sent.

Attached is the log file from HgLab

   Dean,

   You're running HgLab 0.2.181 which is a rather old version. Won't you mind upgrading to 0.3.10?

   I upgraded and get the same error. Log file attached.

   Dean,

   Thanks for updating. That's a strange issue you're experiencing, so please bear with me.

   First, on the server where HgLab is running and open up cmd.exe, cd to c:\inetpub\hglab_home\data\repositories\master\repos\PowerAgent758, run hg verify --verbose and post the output here.

   Next, there's a file named c:\inetpub\hglab_home\data\repositories\master\repos\PowerAgent758\.hg\requires -- post this one here too, please.

   Looks like there is an integrity problem. Could that be causing the error in HgLab?

   Dean,

   Integrity problem indeed. Were you previously pushing to this repository
   via HgLab?

   Yes. I use Source Tree as my client, but use the URL to hglab as the destination.

   Could you please run "hg verify --verbose" on your local repository? If
   it's not corrupt, you delete the ".hg" directory from your server
   repository and copy your local ".hg" directory over to server.

   Thanks. That cleaned it up and I no longer get the error.
