After Last Update not working

I have the same issue, on 3.7.1 “set feeatured image from the first image in the post” is not working. If I revert back to 3.7.0 it works. Running WordPress 5.4.2 on PHP 7.2 and 7.3 on different environments. Looked at the differences and reverting this part of the change fixed it for me

Плагин перестал работать, массово заменяю на всех сайтах на Easy Add Thumbnail. Лучше бы не трогали и не обновляли.

Same case .. please fix it

Thank you all for your feedback. Fixed in version 3.7.2. Please update

Артем, спасибо за исправление багов, заработал плагин, оставляла тестово на одном сайте, проверила, убедилась, что все хорошо, вернула назад на все сайты.

Still not working for me
Plugin Version 3.7.4 in WP 5.5
Hides all posts – leaves only ADD NEW

Hello, @bibliata
Our plugin does not hide posts from the list. Perhaps the reason is something else?

I was thinking the same but after testing with the plugin a dozen times, WP reported critical error each time, so it is the plugin. Perhaps a conflict with a new WP option or another plugin…

If you have seen a critical error, please send the error logs so that I can detect the problem.
