Today I'm having a weird problem:
1. I upload an image (successflully).
2. I try to insert it into a post by clicking "add media" and selecting the image I just uploaded.
3. On the same window, I go to ATTACHMENT DISPLAY SETTINGS and guess what? The "size" field is not there anymore.
I say: Ok, let's try anyway, so I click "Insert into page". I cannot see the image in the post ("visual" window). I switch to the "text" window and, to my surprise, the image attributes are: width="1" height="1". So I change them and now I can see the image.
Next, I try to select the featured image (same uploaded image) and it doesn't show. I publish the post anyway. The post image is there online, the featured image is not.
All this happens only with newly uploaded images.
I'm using a child theme with the latest Customizr.
On the same server, I have a similar website but with Customizr 3.0.13 and no problem at all.
In both cases, WordPress is version 3.8.
"Media" settings are:
Thumbnail size Width:150 Height:150
Medium size Max Width:500 Max Height:700
Large size Max Width:1024 Max Height:1024
