Hello, I may have found a bug but I am not sure.

I was attempting to change the theme to blend more with my site and everything was going fine until I attempted to change the "chat window [maximized]" header text color. No changes took effect when I tried to change it from white to black.

Please see image.

I tried changing it to #000000 but no changes took effect.

We will look into the issue .

Meanwhile
You can directly edit the css file in ~/freichat/client/jquery/freichat_themes/your_theme/css.php
