Problem: After installing the AboutPeople theme and FCKeditor on Drupal 6.9, when the editor is invoked its editor window background is black and the text colour is black, not allowing you to see what you’re writing.
Solution: This is not a problem of the theme or the module, but an unfortunate consequence of their interaction.
Here the fix.
Summary: Go into FCK Editor, change the default style sheet, which is “use theme CSS”, to the “FCKeditor default” style sheet, and the background will turn white, allowing you to see what you’re typing.
How to do it: Admin > Modules > Admin by Modules > FCKeditor > global settings > profiles > edit > CSS. You still with me? Change the dropdown from “use theme CSS” to “FCKeditor default”.
What Happened: FCKeditor defaults to the background colour of the theme, which happens to be black. Your font colour is also black. As you’ve found out, it’s not always cool to be in all black. The change of style sheet to the FCKeditor default put the background to white, so much easier to read if you don’t have ninja skills. You could also try adding your own CSS but that’s too much work and too messy for me. If you could change the font colour to white, the editor would work, but I could not see any such option in FCKeditor. Anyway the web usability of black background with white text would be suboptimal, and would hurt your eyes and tire you out. If you’re over 50 you’d really hate it. It sure does look cool though.
