I have a similar problem, i cannot load up any images, when i click the upload image button which is located at all in one SEO/Social Setting/upload image it takes me to my library, i click on media library and select my image.
Now the pop up shows my selection and i choose the correct size and the only option i see to upload this to my Social Settings is to Insert to Post and when i do this nothing happens. No file is loaded into my Social Settings on that specific page.
Can you tell me what i am doing wrong? The page I am trying to test this on is http://www.boxingbets.com/featured-sportsbook/. My goal is if someone uses the floating Facebook Share link on the top left side that it will pop up the Share box and use the image i am trying to load to the Social medio section of All in One SEO.
Thanks in advance
