Fatal error deleting multiple posts

[bobbingwide]

I got a Fatal error from oik-unloader when attempting to Move to trash 3 block posts. The Fatal was followed by a couple of Notices, a Warning then another Fatal.

URL was https://blocks.wp.a2z/wp-admin/edit.php?orderby=date&order=desc&s=&post_status=all&post_type=block&_wpnonce=3933e1c951&_wp_http_referer=%2Fwp-admin%2Fedit.php%3Fpost_type%3Dblock%26orderby%3Ddate%26order%3Ddesc&action=trash&m=0&seo_filter=&readability_filter=&paged=1&post%5B%5D=10919&post%5B%5D=10918&post%5B%5D=10917&action2=trash

Workaround

Trash the items one at a time.

I got a similar problem when using bulk update > Activate for all the ACF groups in s.b/oikcom

This is now fixed in oik-loader v1.4.1

Retested with v1.4.2 on cwiccer.com, deleting two unwanted posts.
