Great plugin working for CPT

Great, works for CPT, and you can select which CPT will expire (tested with WP 4.9.8)

Uncaught Error: Cannot use object of type WP_Post as array in /wp-content/plugins/wp-post-expires/wp-post-expires.php:287

Just rewrite condition : if($del_post->post_status == ‘trash’){
to : if( $del_post AND ($del_post->post_status == ‘trash’)) { //
