Can someone to help me ?

I verified and there no orphaned entries. Maybe I can grant to you access to admin and FTP and will see by yourself what can do ?

I deleted plugin to re install it. All my galeries dissapeared. How it possible ?
Can I restore them from DB ?

I don’t have this option ‘Galery’ because can’t activate plugin.

add_action('wp_ajax_filter_posts', 'ajax_filter_get_posts');
add_action('wp_ajax_nopriv_filter_posts', 'ajax_filter_get_posts');

this code from functions.php where used do_shortcode

jQuery(document).ready(function($) {
if($('body').hasClass('single-post')||$('body').hasClass('single-huizen-te-koop')){

 
     var post_id  = $('.targetID').attr('id')
    

 $('#tabs').html( 'Loading....' );
        data = {
            action: 'filter_posts', // function to execute
            dataType: 'html',
            afp_nonce: afp_vars.afp_nonce, // wp_nonce
            id: post_id, 
            };
 
        $.post( afp_vars.afp_ajax_url, data, function(response) {
 
            if( response ) {
                // Display posts on page
                console.log(response);
                $('#tabs').html( $.parseHTML(response) );
                tabs();	
                
            }else{ $('#tabs').html( 'Error....' );}
        });

}
});
