Resolved my issue (blank media library).
Steps:
1 – Set WP_DEBUG as TRUE on wp-config.php;
2 – Resolve any “Notice: Undefined index” kind-of-issue
3 – Done!
I did a workaround:
rename /wp-includes/js/media-views.min.js
to /wp-includes/js/media-views.min.js.old
Now the system is loading a old-ugly-version of media library but now it show all images and it is possible to “Set feature image”.
Client is happy for now.
Same here. Having just a blank page and no error is not very helpful.
