New Install - Permissions error (I think)

I have a new install of WP installed.

When I attempt to upload anything using the dashboard.. (Theme/Plugin/media) I get the same error message.

File is empty. Please upload something more substantial.

I have not run into this issue before. so I deleted my cPanel and did a fresh cPanel and started again. Same issue... is this a permissions issue? If so what directory do I change?

Thanks,

Steve

PS. I used an auto WP installer Softaculous
