I've struggled with this for 2 days now and no success. I'm developing a custom module and I'm getting the following error;

Server Error in '/DNN/DesktopModules/myCustomModule' Application.
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Unrecognized attribute 'requestValidationMode'. Note that attribute names are case-sensitive.

Source Error:

Line 174:    -->
Line 175:    <!-- allow large file uploads -->
Line 176:    <httpRuntime useFullyQualifiedRedirectUrl="true" maxRequestLength="8192" requestLengthDiskThreshold="8192" requestValidationMode="2.0" />
Line 177:    <httpCookies httpOnlyCookies="true" requireSSL="false" domain="" />
Line 178:    <!--  GLOBALIZATION


Source File: C:\DNN\web.config    Line: 176

Version Information: Microsoft .NET Framework Version:2.0.50727.3615; ASP.NET Version:2.0.50727.3618

The module works ok until I click a link that brings up a pop-up window that's supposed to display more info for the user. The pop-up comes up but with the above error.
The module is compiled against Framework 3.5 and is running in dotnetnuke 5.6.0 in a developmet machine running Windows XP with .NET framework 2,3,3.5 and 4 installed.
When I delete, the offending attribute in the web.config, it is readded by DNN or another module. Please advise me on what to do. Thanks.

SOLVED. I did several things to make the module work so I thought I should write them down in case someone faces a similar situation in the future. First of all let me note that my module is a modified 'Simply Classified' module which was graciously released open source on Codeplex by Comsite. The original module was not experiencing the same error as mine. I took the following steps.
  • I went to the properties of my website's virtual folder  in IIS and changed  the ASP.NET Version to 2.0.50727 from 4.0.30319. I then deleted the 'requestvalidationmode' attribute in the web.config and this time it didn't reappear again.
  • I now faced another error message 'Could not load file or assembly 'DotNetNuke.HttpModules.compression...'. This dll was right in the bin folder but it couldn't find it. Well it was looking for the .NET Framework 2.0 version. Since I was building my module using dotnetnuke.dll from my dotnetnuke 5.6.0 which uses framework 3.5, my module had to compile against framework 3.5. I then downloaded and installed DotNetNuke 4.9.4 and used the that dotnetnuke dll in my references, dialed back the .NET Framework to 2.0, compiled and there IT WORKED!

DNN 6.1 is developed for .NET framework 4.0, the above solution didn't seem right to me.
What I did instead I changed "Target Framework" of the website to 4.0 and recompiled it, all worked just fine now!

I just changed the. Net framework from version 4.0 to 2.0, and then back from 2.0 to 4.0! And everything worked perfectly!
