Hmm… you’re referring to an incorrect config setting in the php.ini file (not wp-config.php, right)? Any pointers on what to look to change here? I was wondering if there might be a permissions issue with something like upload_tmp_dir (which is currently set to NULL, and so should be using the system’s default), but I couldn’t see how that would explain uploads working on the main site, but not on a subfolder site.

Responding in place of dbeltramo – I’ve been working with him on this issue. I’ve deleted blogs.dir/ and recreated the folder, again assigning the owner and group as apache and assigning 777 permissions. There is nothing under the blogs.dir folder currently. When trying to upload media to a sub-directory, the following error message appears: ““06_Controls.jpg” has failed to upload due to an error
Unable to create directory /var/www/html/wp-content/blogs.dir/2/files/2012/07. Is its parent directory writable by the server?”

Previously, the only things that had been under blogs.dir/ were sub-directories that I manually created to correspond to this file path for uploads. When I manually created (under blogs.dir) 2/files/2012/07, the above error message no longer appeared, but the file failed to upload as dbeltramo described (broken thumbnail and empty sub-directory).

This issue occurs on both of the sites currently created on the multisite install. If it helps at all, a related issue occurs when trying to add an image to a “slide”, which comes as part of a theme installed on a specific sub-directory. When trying to create a new slide and upload an image for it, an error message dialog pops up: “Server error. Upload directory isn’t writable.”

Thanks for your help.
