I am having a problem with a website where files in media library appear blank. This happened after I tried to add a featured image to a post then all the features images attached to the posts dissapeared and do not show and media files appeared like in the image. I have tried deactivating plugins, theme, updating wordpress to different version but nothing seems to work. Do you guys have any idea what it might be causing this ?
Seeing the same issue on my own site. New files uploaded are immediately broken.
*edit* From the wordpress support forum, "Deleting wp-content/uploads/.htaccess worked for me."
