When I try uploading an image to WordPress media library, I get this error message:
“imagename.png” has failed to upload due to an error
Failed to write file to disk.
And sometimes I get an HTTP error.
I am using a clone of another installation that I moved via backup buddy. I had no problems in the original installation until I upgraded to WP 3.5. then I started getting HTTP errors. But when I updated to 3.5.1 it worked temporarily but then I started getting the HTTP errors again and image failed uploading message.
I am not sure what’s causing this and how it can be fixed
Any help is highly appreciated
