If you go to the admin page (or any other page). The color of text boxes is the color from your system theme. (In my case dark) This is especially when I go to edit a wiki page and the color of the text happens to be exactly the same color as the background color from my system theme.
This can be solved by a couple of lines of css:
input { color: black; background-color: white; } textarea { color: black; background-color: white; }
fix in allura:db/3472, and sftheme:db/3472 for the SF theme
