my Modx get lots of php-errors: "cannot modify header info which are already sent"

What plugin has the id 11 ? you can get this by editing the file core/cache/includes/elements/modplugin/11.include.cache.php and looking at the end of line 2

domains/my-awesome-site.be/public_html/core/cache/includes/elements/modplugin/11.include.cache.php : 101

// Don't execute in manager past this point
if ($modx->context->get('key') == 'mgr') {
 	return; 
}

[u][b]header ('X-XFPC-Cache-Active: Yes');[/b][/u]

$cache = true;
$refreshCache = false;

// If posting, don't cache
if (strtolower($_SERVER['REQUEST_METHOD']) == 'post') {
  // Don't cache and remove cached file
  $cache = false;
  $refreshCache = true;
}

Hi Paulp,

Great tip.

I looked into it, and ID 11 is the caching plugin "XFPC"

I opened the

domains/my-awesome-site.be/public_html/core/cache/includes/elements/modplugin/11.include.cache.php : 101

and the "error-line 101" is here now located at line 6, as is shown in the php error:

// Don't execute in manager past this point
if ($modx->context->get('key') == 'mgr') {
 	return; 
}

header ('X-XFPC-Cache-Active: Yes');

$cache = true;
$refreshCache = false;

// If posting, don't cache
if (strtolower($_SERVER['REQUEST_METHOD']) == 'post') {
  // Don't cache and remove cached file
  $cache = false;
  $refreshCache = true;
}
