hi!
i am getting a bit desperate here…

I have a text field, and it saves its value the first time.
After this, when i try to update it, it is NOT saving it…

Here the code of a basic meta_box:

<?php
/*
Title: Box 1d
Description: Links voor box 1
*/

piklist('field', array(
	'type' => 'text'
	,'field' => 'demo_text'
	,'label' => 'Text Box'
	,'description' => 'Field Description'
	,'value' => 'Default text'
	,'help' => 'This is help text.'
	,'attributes' => array(
		'class' => 'text'
	)
));

What i have done?
Updated WP
i deleted all plugins except piklist
i changed to the 2014 theme
disabled its ‘functions.php’
re-installed the latest version of Piklist 9.13
retried other browser

I must be blind, but with this (more then) basic setup of WP it STILL produces no result.
The new value is just not saved.

How can i check its $_POST values etc?
Are there any hooks, so i can dive in even more deeper?
