Wp-discourse quotes unreadable in dark wordpress theme

Hello.

Well, the plugin works, but when a user quotes another, the quote box is white and the text is also white, making it unreadable. Can this be changed?

For quote styles to work with a dark theme, you will need to add a CSS rule to your site to fix the colors of the text and its background. If you can share a link to a post where the problem is happening, someone here can probably help you with the CSS.
