Font turned white on editor's side

I’m building my website FURgeddaboutit.com and everything was fine till the other day I noticed that the font on quick tabs (editor side) has turned to white. It displays properly on the website, but when I go to my dashboard to view what I wrote, it’s all in white. The only way I know that there is anything there is by highlighting the area and than I can see the font. Does anyone know why this is happening?? This is My Life Theme on WordPress
