I just created a new WordPress Blog when I upload images no thumbnail is created and I can't use the images. The images are listed in the library without thumbnails, and the only way I can actually see the image is if I click the "Edit Media" button for cropping/rotating.
I've tried both attaching images to posts and pasting in the image URL with no effect. I've added images to the site's theme folder, and those images can be inserted manually just fine, so the problem is just with the media library.
Any help would be greatly appreciated. I'm terrible with this sort of thing. Thanks.
