I'm getting the following error in WordPress 3.1.4 running in MultiSite mode with Gravity Forms version 1.5.2.8
Upload folder is not writable. Export and file upload features will not be functional.
Based on my searching around on the Forums, I believe this has something to do with where WordPress has the upload folder set for the blogs I have setup but I am unable to determine with certainty where this is set under the Network Admin area.
I have navigated over to the 'Edit Site' area and see the following area referenced for upload:
Upload Path wp-content/blogs.dir/2/files
Is this the setting? If so, it is owned and writable by the user that owns WordPress.
Any assistance would be appreciated. Thanks!
