Ever since upgrading to WordPress 2.7, I am having an issue where I cannot select the "size" of the image I want to insert when uploading through the browser.
Screen shot here:
I manage two wordpress 2.7 sites. One of them is not having this issue -- I uploaded the same picture and was able to resize to "medium". In the screen shot above, as you can see, I cannot select any of the resize buttons, and the full image is shown as "0x0". I can insert the full image just fine.
Image uploading and resizing was not a problem when the site was on 2.6.x.
I imagine this is some sort of directory permissions issue... help please!
