I’m experiencing the same problem: PHP 7.3, WP 5.2.2, ACF Pro 5.8.4, qTranslate-XT 3.6.1
If I deactivate ACF Pro, I can’t see media items in grid view (which means not at all when accessing them via the media uploader).
I get no console errors. Switching debug mode to true yields no obvious PHP errors (other than a handful of deprecated function errors and one ‘headers already sent’).
Help please!
