Setup a virgin install of RC1 today. I then turned on multi-site, created a subsite, and it works pefectly.
However, on the primary blog #1, when I try to add an image via the media manager I get the following error:
“admin-panel.jpg” has failed to upload due to an error Unable to create directory home/wp-content/uploads/2010/12. Is its parent directory writable by the server?
Should it not be trying to go to wp-content/blogs.dir/1/files/2010...?
I noticed there is a blogs.dir/2/ but not a blogs.dir/1/
* the /2/ is my subsite that I added to multi-site, and as I said, that site works perfectly. It is only the 'primary' site that does not work adding media.
