It did not work and now my site won't load  - it gave me an error, so I removed the line.  Now I tried to restart everything, but I keep getting this error now:

(I am running DNN 5.6 on Vista).







What am I doing wrong?  Do I have to re-build the web site in Visual studio after making the change to the web.config file?



Thanks
