When creating a new context, I added site_status. When I choose yes and save I get a "setting_err_nfs" message. Any help would be appreciated! #superfrustrated
As far as I can tell, there's no such error. I think you mean setting_err_nf. It's a confusing message ("Setting not found") that often means MODX couldn't find the Context itself.
Try creating the context first, saving it, clearing the cache, then re-editing the Context and adding the setting. I suspect that MODX is trying to set the setting before it's aware that the new Context exists.
