I have a Wordpress multisite installation
I just recently upgraded the Wordpress version to 3.5.1.
Since the upgrade I see the following message on my admin dashboard
"Upload folder is not writable. Export and file upload features will not be functional."
If I de-activate the Gravity Forms plugin. The message disappears. When I activate it again, the message appears again.
I also see this message on the individual sites in the network.
I have checked the file permissions and I have even changed them to 777 and the error message is still there.
