For some reason when I created my Wiki site, Upload File was not an option under Tools. How do I make it an option?
Topic on Project:Support desk
Probably need to set $wgEnableUploads to true.
MW 1.34.2: Same problem here. I cannot even add it manually to the Sidebar.
I have the EnableUploads set to true. Even attempting to add Special:Upload with or without brackets does not work.
