I added a chatbox to my site. Me and my friends played with the colours for a little bit. When we tried to switch them back to default, we couldn't. Why is that, what can we do to turn the colours back to normal?
(setting it white again doesn't help, we can't see what we type in the text bar).

The forumotion chatbox or chatango or another third party chatbox?

Default forumotion chatbox.

Your chatbox color is same as your main background.
Go to Admin Panel > Display > Pictures and Colors> Colors > Background Colors > Background Color :

If it was that easy...
Uh. When I log on the chat the font colour is default, white on black background. Also the typing bar is whit, but there letters are black on white background. And that,s by default.
After changing colours the colour both in the chat and the text bar below is the same. Switching it back to white doesn't solve the problem, because although ot is white in chat like it used to be, I can't see what I type in the textbar, cause the letters are still white, like the background.
The point is: is there any simple way to turn the colorizing tool back to default, so the letters in the chat would be white and in the textbar black?

If that does not help, please provide a forum url with the screenshot & let us know the colors that you need to change.

You can try Checking your drop down menu box/color as well.
You do not want that the same color as your default text.
