upfront won't show me the media library when clicking "select picture"

hello heroes.

ok - so on the above site, where i have enabled support, when loading upfront, and trying to edit the front page pic, i can click on the edit the section blue triangle, and fidget with options, but hwne i try to select an alternate pic, and it usually goes fuzzy and brings up the dialog box to show library / upload?

yeah - it just goes fuzzy.

it is a FRESH wordpress install, and FRESH wpudev dashboard / pllugins / themes install.

pls have a lookie see?
