I installed the upadate and made the changes to the web.config.  But now when I try to go to the web site I get errors. see below...

Server Error in '/' Application.

The first time the error showed up it was with IFrame and ALTBGallery.  Interestingly when I use the previous web.config I can go in and uninstal the ALTBGallery module and I uninstalled the Iframe module.  Still getting this error.  the site works, mostly, with the old web.config but I can't creat new pages.  So how badly did I screw up?

Version Information: Microsoft .NET Framework Version:2.0.50727.1433; ASP.NET Version:2.0.50727.1433

That fixed one problem, but introduced a new one.  When I go to the site after making the changes to the web.config I get a site is unavailable error.  then when I try the second time, refresh or whatever I get:

Changes I made to the release.config/web.config are:

I changed the database name, user name, password in the two locations. (line 30 and 38)
Changed the Validation key, encryption key.  I left validation and decription as they are the same. (line 66-69)
Added code subdirectories to line 126-127; they where html, reports, survey, xml, altbgallery, chat, iframe

would it help to post the whole web.config minus user/password?

Thanks
