OK, I've read all the posts that concerns my issue/error/bug but nothing is working.
Installed WordPress 3.5 but can't upload media. I get the errors "Error saving media attachment" and the other one which said there isn't a folder. The posts I've read (from 2/3 years ago) are saying that you should add a uploads folder (so I did). Then they say change 755 to 777 (so I did). Go into media settings of WordPress and change the directory where uploads should go (there is no such thing in the settings of WP 3.5). Tried with the year and month checked. This created the folders 2012>12 but no upload possible and still the same error.
Can anyone please be my hero and help me with this 4-days struggle?!?
