you have two background rules in your CSS
HTML Code:
margin: 25px 0; padding: 25px; background: #FAEBD7; -moz-border-radius: 8px; -khtml-border-radius: 8px; -webkit-border-radius: 8px; border-radius: 8px;
padding: 25px;
background: #eee;
-moz-border-radius: 8px;
-khtml-border-radius: 8px;
-webkit-border-radius: 8px;
border-radius: 8px;
my guess is that the option field is only showing 1 line right? and you coded your options on it.
There seems to be a problem with some plugins and wordpress causing this one line issue. The option box should have three diagonal lines on the bottom right side so you can make it bigger.
For teh time being, put your cursor in teh box and doa select all, then a copy and go to a text editor program and doo a paste. you will see all the options. You can adjust them there and thencopy them back into the option.
Try turning off your plugins to see if that fixes teh 'one line option' problem
