I happen to resolve my Media Uploader issue with some CSS added via admin_head — after testing via a few different WP “Single Site” cases on my VPS to fix an issue on a clients WP Multisite.
• This code fixes the “Media Uploader’s” content visibility.
• This fixed the issue when tested on separate installs and cases for WordPress 5.9 – 6 “Gutenberg Blocks” and Advanced Custom Fields Pro “Blocks” 5.10 – 5.12.2.
Here a snapshot:
Now I may proceed with using ACF Blocks and Inner Blocks!!!
I have been persistent on fixing my issue for the past few days and I hope this helps someone.
