Дайте мне знать, если это работает или нет!
The image that is not showing for me has this location!
wp-content/uploads/2019/02/spring.png

I have to check, Whether the permission for uploads folder, 2019 folder and then for
02 folder are same or not
Go to your wp-content folder

Then check each folder permission they have to be the same!

In my case they are same now go to your database and delete the upload path in your
wp-database option
Go to wp-options and look for upload path, it can be on the second page also, search
for it
cut the path and paste it somewhere else, and make the path empty
Теперь снова загрузите изображение и посмотрите, будет ли оно отображаться в библиотеке мультимедиа.
