If you're using header("Location: ");after you've output content make sure you've put ob_start();earlier in the script. ob_start();buffers your script, so nothing is output until you either call ob_end();or the end of the file is reached. Calling header("Location: ");after content has already been output to the browser can cause problems.
如果您在header("Location: ");输出内容后使用，请确保您已将其放入ob_start();脚本中。ob_start();缓冲您的脚本，因此在您调用ob_end();或到达文件末尾之前不会输出任何内容。header("Location: ");在内容已经输出到浏览器之后调用可能会导致问题。

Put ob_start();in beginning of PHP file , it will helps,
把ob_start(); 在 PHP 文件的开头，它会有所帮助，
<?php
ob_start();
/*
Your code
*/
?>

Make sure to put an exit; or die; after the command: and make the "Location" start with uppercase
确保放一个出口；或者死; 在命令之后：并使“位置”以大写开头
if (!isset($_SESSION['SESS_MEMBER_ID']) || (trim($_SESSION['SESS_MEMBER_ID']) == '') AND !isset($fb_login)) {
header("Location:login.php?msg=Please+Login+Again.");
exit;
}

Make the Lcapital.
做L资本。
header("Location: login.php?msg=Please+Login+Again.");
exit(); // just a precaution
回答by Jon
Try formatting the header correctly:
尝试正确格式化标题：
header("Location: login.php?msg=Please+Login+Again.");
And of course make sure that you are not sending any output (either on purpose or by mistake) before the call.
当然，请确保您在通话前没有发送任何输出（有意或无意）。

1)Be sure that you do not send anything before the header() function
1)确保在 header() 函数之前没有发送任何内容
2)Make "location" to "Location: "
2）将“位置”改为“位置：”

Adding to what others have said, are you sure that the cnditions are met to hit the header()
添加到其他人所说的内容，您确定符合条件以击中 header()
You could use empty() to clear up your code & Do some testing :
你可以使用 empty() 来清理你的代码并做一些测试：
//Debug
unset($_SESSION['SESS_MEMBER_ID']);
unset($fb_login);
if(empty($_SESSION['SESS_MEMBER_ID']) && !isset($fb_login)) {
exit(header("Location: login.php?msg=Please+Login+Again."));
}

Try changing the ANDfor &&
尝试更改AND为&&
if(!isset($_SESSION['SESS_MEMBER_ID']) || (trim($_SESSION['SESS_MEMBER_ID']) == '') && !isset($fb_login)
) {
header("location:login.php?msg=Please+Login+Again.");
}
