pasted code in html, now cannot login.

I got some code from ThemePress to insert into html to help my site. I tried placing in an area in Theme Functions (php or css, I think) where they say to put any custom code ‘below this line’ It did not work, so I removed it.

Now, When I try to log in, I get this on the top of the page that I login on:
Warning: Cannot modify header information – headers already sent by (output started at /home/content/86/8096986/html/wp-content/themes/Karma/functions.php:14) in /home/content/86/8096986/html/wp-login.php on line 349

Once I type in my admin name and password, I get:

The only other piece of information is that stressprofessionals.com works fine, whereas http://WWW.stressprofessionals.com does not??

I was able to get in to my FTP manager at my hosting account, and tried to reupload the theme, but nothing happened.

Help??
