Ask: Postdata has expired from chace

[junandya]

Hi,

I want to ask, why every i click a button and move to another page this popup always appear:

The page you are trying to view contains POSTDATA that has expired from chace. If you resend the data any action the form carried out (such as a search or oline purchase) will be repearted. To resend the data, click OK. Otherwise click cancel.

It seem, because this, my redirect script is not working properly.

Please explain me what is the matter with it and give me the solution to solve this problem.

Thank you B4

I guess you mean the "back button" on your browser?
