A quick work around for this problem is described here at this link https://www.ads-software.com/support/topic/wp-44-you-are-not-allowed-to-manage-these-items?replies=10#post-7755373 I have solved the issue by changing the code.

$this->_cp_proprieties = array(
			'_builtin' => false, // It's a custom post type, not built in
			'supports' => array('title', 'editor', 'thumbnail', 'excerpt', 'custom-fields', 'comments'),
			'public' => false,
			'show_ui' => false, // UI in admin panel
		);

change ‘show_ui’ from false to true.
the above code can be found at the path /htdocs/wp-content/plugins/enhanced-category-pages/classes/ecp/Enhanced_Category.php

hope this might help anyone.

me.. too having the same problem.
I love the plugin.. it does exactly what it says prior to wp v4.4. After updating to 4.4 we are unable to edit it.

I had the same issue with the CPT-onomies WordPress plugin….
The code above mentioned by @michael Beckwith has worked for me but with a slight change for CPT-onomies plugin..

The code I used is given below

#Open cpt-onomies/manager.php through your WordPress dashboard (Plugins > Editor > cpt-onomies/manager.php )

now search for below lines

// register custom post types and taxonomies
		add_action( 'init', array( &$this, 'register_custom_post_types_and_taxonomies' ), 100 );

change last parameter 100 to 1 in the above code and then save the file.

now you can also see your custom post types categories in all the VC blocks that you want to use in your pages and posts

Hope this helps for people who use CTP-onomies and VC plugins together
