Having problems with only 1 of my many wordpress multisite subsites. I'm using a plugin called Sermon Browser and it works great on all other subsites except 1 of them. When I try to upload a file using it, it tells me that "Upload is disabled". I cross referenced the problematic site's settings with another site where the plugin is working and the only difference I can see is that Fileupload Url is missing and on the site where it is working it shows up.
I was going to post this question under plugins but I don't think it has anything to do with the plugin.
