Media files not appearing.

This probably just occurred today:

I am writing a new post for my site, and when I wanted to add an existing media file (image to be exact) from the library, nothing appears. However, the count for all the files is stated as 4300+ but none of them showed.

Then I went to the library link, and all it says is “No media attachments found.” when I am viewing under “All” instead of specific file types.

However, none of the images on the site appears to be broken.

Can anyone help me with this? MUCH APPRECIATED!
