Allow access for WordPress editor to the Flamingo CF7 database

functions.php

<?php

function fl_map_meta_cap($meta_caps){
	$meta_caps = array(
		'flamingo_edit_contact' => 'delete_pages',
		'flamingo_edit_contacts' => 'delete_pages',
		'flamingo_delete_contact' => 'delete_pages',
		'flamingo_delete_contacts' => 'delete_pages', //May not be a thing???
		'flamingo_edit_inbound_message' => 'delete_pages',
		'flamingo_edit_inbound_messages' => 'delete_pages',
		'flamingo_delete_inbound_message' => 'delete_pages',
		'flamingo_delete_inbound_messages' => 'delete_pages',
		'flamingo_spam_inbound_message' => 'delete_pages',
		'flamingo_unspam_inbound_message' => 'delete_pages');

	return $meta_caps;
}
add_filter('flamingo_map_meta_cap', 'fl_map_meta_cap');

this snippet will enable all wordpress backend for every registered user...

DO NOT USE !

@themaniac Could you explain more about that?
If you are a register user, you have basic access to backend always , but without any important permissions. Thats normal

@kanlukasz if you use this snippet, users with editor role have the same backend options as administrators...

That's exactly what I needed, thanks OP.
