I keep getting this error message whenever I am trying to update any content. I am using latest version of mojoportal, I see on few posts that this can be resolved by giving permissions to temp folder.

What temp folder is it? I am not sure if I can do it because I am using a shared hosting, can someone please give more info on this?

Server Error in '/mojoPortal' Application.
