Change Book Cover Image

Hi,

I am not able to change the book cover image, neither by uploading a file nor by selecting one from Media Gallery.

When I try to upload, I get an “upload error” message, and when I try to select from Media Library, it just shows the default ‘loading” wheel and never show any images.

I am using a genesis theme.

Any idea why?

Also, is it possible to remove the counting from social media sharing buttons? keep the buttons, but remove the count.

Thanks
