Include php

[vbronald]

- Plugin
I have made and activated a Plugin with the flowing information:
Hook Location: global_start
Title: btnSolvedPHP
Execution Order: 5
Plugin PHP Code:
ob_start();
include('customcode/btnSolved.php');
$includedphp = ob_get_contents();
ob_end_clean();

- Template
Then in the default template I've set the $includedphp at the right place:
So in 'postbit' right under '$template_hook[postbit_userinfo_right]' I add the line '$includedphp'

- File
In the file 'customcode/btnSolved.php' I put the folowing testing-code:

PHP Code:

<?php
echo 'qqq';
?>

- Result must be that in a post header right under the postcount there has to be a line 'qqq'.
But that is not the case fortunately.

When I change the plugin-code to:
$includedphp = 'qqq';
there is olso no line shown.

Plugin-system is enabled and the plugin is also enabled. File and folder rights are 666.
What can be the problem here?
