How to return a value from a database meta_value in Wordpress?

There are Unyson wordpress framework, powered by bootstrap. Supports extensions and custom options.
There is a Mega Menu extension, which contains 4 types of menu items - item,column,row,default. Inside each you can add your option in the form of ass. the array in my case :

$options = array(
 'item_thumbnail' => array(
 'type' => 'upload',
 'label' => __( 'Image', 'fw' )

technical documentation is written to return the value you need to call the hook `fw_ext_mega_menu_get_db_item_option($item_id, 'default')`
But I have returns an empty string. If I call the array of default options it gives me
 [item_thumbnail] => "

While in the admin the image is saved and if you refresh the page, it is.
I decided to look for the option item_thumbnail in the database and found the meta_key

and meta_value to him

Ie the value in the array of options default is, and contains the array key is the url and link to the file.

WordPress is itself a framework. But the garden that you have written a piece of rubbish.
Developers need to promote it - even if they support it and do write them.
