My paragraph font has gone blue and centered and I cannot change it back

My paragraph font has gone blue and centered and I cannot change it back. The settings seem okay.
Also the Justified button has gone from the visual editor toolbar.

When I justify, manually, it ends up centre. So I have to use left align. I can change the color if I highlight all the text and change color but the default was black.

Any ideas please, it is site wide issue.
