View State Error

Recently i've been recieving this Error message

The viewstate is invalid for this page and might be corrupted.

I can't see why this is but it's only just started happening, any idea's what might be causing this?

Cheers.

PS. enableViewStateMac = false on the page where the errors occur.

Bump.

This is still happening and i'm at a loss as to why, any idea's anyone?

ViewState is always tricky to get a hold of... I myself, have never experienced it, and I wonder what special things you may be doing in your app that cause this.

While you formulate a response, see this:

http://aspalliance.com/articleViewer...aId=135&pId=-1

i can't get any of the articles to display at aspalliance, just keep causing application errors, i'll try again later.

I am sitting with the same problem, did any one of you find the solution for it.

I am calling a .aspx page in another using the server.execute("pagename.aspx",true)

and it displays properly, but when the form (with runat=server) in the "called" page is submitted, it displays me the error posted by FISHCAKE in his first post.

thanks.
