I get this message when I try and upload an image:
Unable to create directory /home/wpcom/public_html/wp-content/blogs.dir/7d7/726277/files/2007/01. Is its parent directory writable by the server?
Is that end question meant for me? O.o
Just in case any of this helps as to how I got that message:
-I uploaded a picture, and was about to crop it but it wasn't the right siz so I clicked back on my browser.
-I went and edited my image.
-Went back to upload the same picture (different file though) then I got that message.
