"Failed to write file to disk"

I’m having an issue - where when I upload an image I get the message “failed to write file to disk”. This seems like a permissions issue but I can’t find within the Kirby panel where to check or change this. I should note I didn’t build the website- I’m only a user to update the images/content. Thank you so much for your help!

This could also be an issue with insufficient disk space. I’d get in touch with the website admin or contact hosting support.
