Thread:Project:Support desk/Cannot upload images to wiki, "Could not create directory "mwstore://local-backend/local-public/"

Whenever I try to upload an image to my wiki using the upload image finction, I get the error "Could not create directory "mwstore://local-backend/local-public/c/ce"

I'm new to this whole thing, and was wondering what was causing the problem and how to fix it.
