wpDiscuz background turned dark when I add in Super Socializer as well

I'd installed Super Socializer as an add in for the social login. Unfortunately, this made the Discus background turned dark.

Ie, the usual reply cells etc that could be controlled by the Styling tab are still the same but the box outside of it in black. This made some of the words hard to read because my original option was dark text on light blackground, but this turned it around.
