I tried to access my site and got an error. It was the last dnn prior to 5.6 It seemed to be working fine untill today, I have made no changes to the server or the app except to put the app pool in IIS to .net 2 from 4.

After the problem appeared I restored the data base and the the file system through xcopy. with the same results and error.

I also tried commenting out the offending line with  some more obscure (to me) result. so  i put it back and here I am.

This is a critcial enough issue I am considering giving up on this  app for further use....i dont know where it came from or why normal back up processes have not recoverd :

Server Error in '/' Application.

When you changed the AppPool from ASP.Net 2.0/3.5 to 4.0, a number of changes would have been automatically made to the web.config file. The addition of the requestValidationMode="2.0" attribute to the < httpRuntime > node would have been one of those changes. Apparently, either the modified web.config file was restored or if the site files was restored with the AppPool still set for ASP.Net 4.0, the same web.config changes would have been made again automatically. Since the requestValidationMode attribute is not compatible with ASP.Net 2.0/3.5, you are seeing this error. After confirming that you have switched the AppPool back to 2.0/3.5 you will need to restore the web.config file from the backup made prior to changing the AppPool to 4.0. If you do not have a backup web.config you will manually need to revert the changes made for 4.0. One of them will be to remove the requestValidationMode="2.0" attribute from the < httpRuntime > node. There would have been two other changes made to the < runtime >< assemblyBinding > nodes relating to binding redirects for System.Web.Extensions and System.Web.Extensions.Design assemblies. Changes made for ASP.Net 4.0 should be commented in web.config so should be easy to find.

looking over some of the other posts that seemed  related by the downgrade from .net 4 to .net 2 I tried  removing the offending

attribute 'requestValidationMode'.

I then get this:

Security Exception

Thanks for your input.

I did a restore again, this time under .net 4, and am able to bring the site up.

I am not sure where to proceed from here.

should I try to get it back to .net 2 ?

should I try to upgrade to 5.6?

I need a stable platform for a good client.

Perhaps it will work as is, but I have to be up and running well in just a few more days.

any Ideas?

Thanks again for the input.

If the site appears to be running without errors (check Event Viewer to see any errors that are being logged) under DotNetNuke 5.05.01 and ASP.Net 4.0, I would be tempted to leave it as is for now as there is a know issue with the 5.06.00 upgrade/install relating to the URLRewriteModule that is affecting some sites.

On the otherhand, a low-level security vulnerability with DotNetNuke 05.05.01 and prior versions was just announced and was fixed in 5.06.00. Here's the blog post describing that issue: http://www.dotnetnuke.com/Resources/B...

If you do upgrade to 5.06.00, be sure to make a good filesystem and database backup first in case you have to roll back.
