Hello Tara,
thanks for your advice.
I’ve changed wp_content folder permission to 755. In a similar topic thread someone suggested to erase uploads folder, cause wp would recreate it by default once you upload something. Which I did, but it didn’t happen: there’s no uploads folder, and this is the message I get when I try to upload media: “Unable to create directory wp-content/uploads/2013/07. Is its parent directory writable by the server?”
Not sure what this mean, but I guess wp-content is the directory mentioned?
