WP_List_Table error on WordPress 4.4

Heyaa…,

I’ve found a final answer, hufft…

Yeah, first I include the necessary classes just like in this thread :
Fatal error after 4.4 upgrade class-wp-list-table

And second, I added up this line in the display_tablenav method in WP_List_Table class :

$this->screen = get_current_screen();

before this line :

$this->pagination( $which );

That added line create a WP_Screen instance for WP_List_Table’s $screen. Well, the secret sauce is at WP’s get_current_screen() function.

Thanks all.
