• I converted a WordPress Multisite from sub-directory to sub-domain. Everything is working with the site except it will no longer create image sizes.

    When I upload any image to a post or a page it only gives me the option of embedding the “full size image”. I have checked the media settings, and I have settings for thumbnail, medium, full, etc. but it is not create the sizes.

    I have tried:
    -Tried installing the WordPress 2014 Theme (it’s not my theme)
    -Disabling all plugins (it’s not any plugins)
    -I have checked the folder where the image is uploaded and, yes, it only uploads the image and it does not create any other image sizes. (it’s actually not creating the images, it’s not that the options just aren’t being displayed).
    -I have ran WP_DEBUG, and there’s nothing wrong with my site

    What else can I try??

    Thanks!

  • Did you ever solve this ?

    I have the same problem on a sub-directory multisite install. I have custom image sizes, but looking on disk, WP does not create *any* sizes. Only the original upload is there. WP 4.0.

    I use the same theme on a separate single site WP install, and image sizes all work fine there. Must be something to do with multisite ?

    Turned out I did not have GD support installed! I’m using nginx/PHP-FPM and (unlike Apache/PHP) it seems GD is not installed by default, which caught me out. Hope it helps someone else!

    Cheers,
    Jack
