Error Uploading Images in WordPress

I have a couple of WordPress sites hosted on GoDaddy.  ONe's working fine.  The other, I'm getting this error message Uploading media.


Unable to create directory uploads/2017/01. Is its parent directory writable by the server?


What does this mean?  How do I solve this? I had no problems creating my other site.  I am taking over from previous person who started this site.  Theme is Twenty Thirteen I think, but same when I changed to other themes.  Thanks.
