I have a Multisite setup and one of my blogs has an issue where the posts for Nov & Dec 2011 have their attachments being uploaded directly to: blogs.dir/SITE/files not blogs.dir/SITE/files/year/month as I use on my setup.
Might have mistakenly turned OFF the use Month/Year folders option for Media Files for that site between that period.
I am attempting to fix it and have done the following but URLs in the Media Library & Media Uploader still refer to the old path.
1. Edited the Attachment GUID in the correct wp_SITE_posts table to use the new preferred path (blogs.dir/SITE/files/year/month)
2. Moved the image files from the OLD folder to the NEW Folders absed on Year/Month setup.
3. Edited Posts with that issue so their content reflect correct paths to images/media attachments.
Although inline media in posts show up correctly, Media Library & Media Uploader still show the OLD paths.
