Hi Matt,

Thanks for reporting this.  I have seen this error a couple of times with the v2.2 beta.  However when I try to debug it, the app-pool is restarted and the error goes away - unable to reproduce the error again.

Try touching the Web.config or restarting your app-pool, that will clear the problem for now.

If you know of a way that we can reproduce the problem, let us know ... we'll get it fixed.

Thanks, Lee.

Also experiencing this problem. I have xslt search, gecko uploadify and ConfigTree installed and using the Business site starter kit.

Thanks

Same problem here. Restaring IIS fixes it.

Request Url:
