I set the permissions for the folder "wp-content/gallery" at 777 and for all the sub-folder (I belive that don't need this full permissions, what is it the minimum?).
In General options I have selected the default GD library.
I belive there isn't problem, but when I load images or try to re-create the thumbnails I receive a generic error message without details.
The image was uploaded, the subfolder for thumbnails was created but the thumbnails files not.
What can be the problem?
Thank you for all. Giuseppe.
