Hi

I upgraded to DNN 7.4.0 from DNN 7.3 and the URL rewriter does not work at all. I had to change my webconfig to switch back to the core rewriter, however now I get this error if I go to the Portals Admin page:

It looks like someone else has an error but this post if no loading as the DNN Forums are broken:  http://www.dnnsoftware.com/forums/threadid/515139/...
