    I got the same error much times, 99% it's caused by other outdated plugin. The only solution to understand what's the problem is to backup everything, then deactivate all plugins. Try them to re-activate one by one while testing image upload till you find the bugged one! Try also using plugin such as DB-Spring-Clean to ensure you removed all old plugin records in your database. Try also moving website to another provider in the end (maybe a test area)

    Hi, I had similar problems but I was able to get rid of them by removing unnecessary empty spaces in my theme's functions.php. Unbelievable but true!

    My problems were:
    - When I added new images in media library (via Media library or post or page) the WordPress gave me error messages. Still the images were added successfully in the library
    - When I used Add media -button in post or page, WordPress couldn't find any of my images in the library -> it just showed empty
    - When I added new images in Nextcellent gallery, I received more error messages
    - The edit thumb -function didn't work at all in Nextcellent gallery

    And my removing couple of empty spaces in my theme's functions.php file, all these errors disappeared !!! Weird. I hope this helps some of you too.

    I have the same error.

    I tried with other explorers, desactive all plugins, reinstall theme, reinstall wordpress... and the problem continues.

    Also, I found that WP help:


    I followed all steps, until step 4, is that. The diagnosis step 3 show me that warning:

    "JQMIGRATE: Logging is active"
    JQMIGRATE: jQuery is not compatible with Quirks Mode
    consider using 'dppx' units, as in CSS 'dpi' means dots-per-CSS-inch, not dots-per-physical-inch, so does not correspond to the actual 'dpi' of a screen. In media query expression: print, not all, (-webkit-min-device-pixel-ratio: 1.25), (min-resolution: 120dpi)

    Thanks MacManX.

    It was done:


    But in that there are a lot of people opinions, so I decided to answer.
