Whenever an admin tries to edit the content of an webpage, it throws this error - "Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode". Also the stack trace gives me the following details - [SerializationException: Type 'DotNetNuke.ContentManagerSecurity' in Assembly 'ContentManager, Version=4.0.0.41358, Culture=neutral, PublicKeyToken=null' is not marked as serializable.] I have searched Dotnetnuke Project and I cant seem to find the assembly Content Manager. I am using DNN version 4.3.5. Any thoughts/ideas? Thanks in advance.
 

Yes..i just found that...i used reflector to see whats inside the dll and bingo...there is this class called "ContentManagerSecurity" which is causing this problem...i have about 4-5 session variables inside my application...so what is the best way to handle this?
