Content and UI style/color issues (Headers dont work, white on white)

Hi here’s a summary of my issues XD

  1. When I copy and paste content that is black text AND I am using a theme with a black bg, my text is invisible. I have to change the text from the source to white before pasting it in because I have no text color options. (USER TOO STUPID?)

  2. UI. In various places such as when you add an image,
    the text is white and the bg is white.

Where does one fix this? Which theme are we using? How do I find out the current theme?

  1. Source view: When I click source, the text is white and the bg is always white. Is this possibly someone has poked around in the CSS and broke it? Or has anyone else come across this?
