Jetpack Comments White Box Problem

I just looked at your site and can’t see a white box. All I see is a sentence, saying that I need to login to leave a comment.

Oh yeah. I’ll change that so you can see, sorry.

I’ve tried reinstalling Jetpack but it didn’t work by the way.

I think that the reason why there’s a white box is because jetpack has the body set to white.
I’m not sure there’s any way to overwrite that. Do you have to use jetpack for comments?

Well I don’t see why I shouldn’t use Jetpack comments because it has never done this before. It only started 1 or 2 days ago. If it only started 1 or 2 days ago, then something must have caused it to change, therefore it must be reversible.

Am I missing something, or can you just override the white with CSS in Jetpack’s Custom CSS section?
E.g,

.highlander-dark {
background: #343434;
}

I tried that, but it didn’t seem to work.

It is set to the Dark theme by the way, and although the rest of the theme changes when I change the theme it in Discussion settings, the white box still stays.

try adding !important on the end of the style;

.highlander-dark {
 background: #343434 !important;
}

I tried that, but it also didn’t seem to work.

It has a warning symbol on the line of “!important” saying “Use of !important”.

Is there anything else I should do? Something must have caused it to randomly have a white box. It worked absolutely fine before.

Something seems to have fixed the problem. I deactivated the SI Captcha Spam plugin and the white box disappeared. I then reactivated it, but it didn’t come back. I don’t know if it was this plugin that caused it, but it works now, and that’s what matters ?? .
