Edu-clean child CSS problem


I am having trouble changing some themes options in my Edu-clean Child theme.

I have changed the adminbar background color, and top header text color in
theme options, neither is responding.

I inserted my header secondary text *for logged-in user only (which DID work)
Then, I inserted my header main text *for non logged-in user only (which DIDN'T work)

Next, I tried deleted the theme altogether, and reinstalled a new edu-clean (and child) theme
folders, but it made no difference.

Yes, I have cleared the browser cache.

NOTE: I do have a test install running and it's working fine there. But I have have no idea
what's wrong with my main site)

Any other suggestions?
