Any!?

Reinstalled application and created new samples database using standard theme. Still getting redirected to error page and system log:

"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."

Does error reside in application or hosting server?

Feel free to test at:

nopCommerce 2.00-2.30 doesn't allow session storing in 'StateServer' and 'SQLServer' mode. This bug is fixed in upcoming 2.40. See changeset a8644bd18ab4

Did you change your SessionStateMode  (web.config)?   This error is not an NopC issue.  I recommend you google the err message and look responses in other forums (e.g. http://forums.asp.net/t/1309558.aspx/1 ).

Also, did you ever try running on your local pc?

I need to confess I'm coming from the "Classic ASP" world and .NET understanding is still very limited.
I have not made any changes from downloaded files and application works on local pc (win7, IIS7, SQL Server 2008).

Correct me if I'm wrong but are theese my alternatives...
1/ Wait for release 2.40
2/ Notify hosting provider (being a server issue)
3/ Add statements in web.config

Please be patient with my lack of knowledge.

1. Yes, you can.
2. No, it's not a server issue, nopCommerce just doesn't support this option yet. I'm not sure that your hosting provider will agree to change it for you (it depends on provider).
3. Yes, you can.

Awaiting release 2.40 may take weeks or months?

Can any advice workaround statements in web.config?

Please see my post above. I would suggest you to apply this changeset and the issue will be fixed (but it requires some developer skills).
