CMS security token missing.
 

<div>I have searched the forum, and found some threads about this, but none of them applies to my problem. (as far as I can understand).

I have created a widget (PHP Direct Execution) with this content:
PHP Code:
// UNTESTED
ob_start();
include("test/addApplication.php");
echo "\n";
$output .= ob_get_contents();
ob_end_clean();

the file (addApplication.php) that the widget refers to is this:
<div class="bbcode_container"> PHP Code:
<span style="color: #000000"><span style="color: #0000BB">
