PHP Notice: Undefined index: cpt in wp_ajax_wpae_filtering.php on line 53″

hi i try to use your tool but i get wp-ajax.php 500 error after i select the type of importing object.

From my debug log i can see this:

“PHP Notice: Undefined index: cpt in /var/www/vhosts/centroaccessori.eu/httpdocs/production/wp-content/plugins/wp-all-export-pro/actions/wp_ajax_wpae_filtering.php on line 53”

i try with two different hosting server but result is the same.

There is a tool to know wp all export requirements?

regards
