A few days ago I attempted to update my blogs to version 5.2.2. There was a conflict with Sucuri Plugin and the attempted updates resulted in errors making the sites not accessible.

I then did a clean, manual install of 5.2.2 and everything is fine on all sites except one. The Media library does not show up in the editor and some of the media files are not loading?

The media folder is intact via ftp, but when I click on Media Library in the WP dashboard sidebar, just an empty editor page opens, there is nothing listed in the Library.

Meanwhile “most” of the images are loading, but there are some which show up as missing/broken.

What is the best way to try and diagnose this issue?

Thanks very much
