Image Uploads as 1×1 px, Size not seen in DB

  • Okay, I have been having a lot of problems with one site on a VPS server that was duplicated by our tech support for both in FreeBSD and ubuntu. The images when uploaded are not visible in posts and are written as 1×1 pixel in size. The image sizes are not in the database, and when you click on the image to edit it, it says “image does not exist, please re upload …” BUT The image is clearly visible in the media library.

    I am not the only one having this problem. I read on another thread that a fix is to add the path in the wp-options table to the upload_path value.
    However, when I look at all my WP sites, even those working properly, NONE of my sites have a path value … they are all empty. Now some of these were updated from previous versions of WP, but the site which is not working was a fresh install of version 3.8

    I have: deactivated all plugins and used default theme but that does NOT fix this issue.

  • I got the same problem after upgrading WP from 3.6.1 to 3.8.1.
    It looks like there was a change in wp-includes/media.php function wp_constrain_dimensions(): width and height is set to max(1, $current_<w/h> * $ratio). I have changed:

    $w = max ( 1, intval( $current_width  * $ratio ) );
$h = max ( 1, intval( $current_height * $ratio ) );

    to

    $w = intval( $current_width  * $ratio );
$h = intval( $current_height * $ratio );

    as it was in v3.6.
    It’s a hack rather than fix, so do it at your own risk.
