have you done any redirection in your code but you still try to respond out something after that?
David FavorLinux/LXD/WordPress/Hosting SavantCommented:
This message means exactly what it says. The request triggered the HTTP header set to generate, then a duplicate header set was generated.

Here's how I fix these problems.

Visit the your problem link using...

curl -I -L $URL

Open in new window

Take a look at the headers.

Then run your /home/**********/createaccount.php file on the command line. Likely this command will die, unless you've dummied up whatever Web server environment is required + also likely you'll see two sets of headers emitted.

If you compare the curl output + .php file output you can get clues to fixing the problem.

If your php.php is the root of your request (no other include files), this becomes easier, as the problem should be easy to fix.

you can use the header function to do redirection in php and you're unnecessarily to do a redirection by writing javascript to do that.


in your case, you may put the exit after the last echo.

                                          echo '<script type="text/javascript">';
                                          echo 'alert("saved successfully...");';
                                          echo 'window.location.href = "packages.php";';
                                          echo '</script>';
