The page you requested was created using information you submitted in a form

How to get rid of:

The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you.

I'm using this code to go back to the last page visited
[code]
<input type=button value="<< Back" onClick="history.go(-2)" />
[/code]

You can't "get rid" of it since it's controlled by the browser.
The only way would be remove the form that submits data to the page you are trying to make the browser go to.

that is a feature built into your browser. you may be able to change that in your browser options/preferences. it's a "security" feature because if you were say, using a public computer and entered in personal info into a form, some other person could come up later and use the computer and just click the back button and get some of your info.

this is in no way shape or form a php related question. even your code is js, not php.
