reverted to 4.2.2 and now I can't login to wp-admin

Hey there,
I'm hoping you can help. I had to revert back to 4.2.2 because of the new shortcode api thing. Anyway, now I can't login to one of my sites. I'm getting this error when trying to go to the dashboard: Parse error: syntax error, unexpected $end in /home/content/43/10010643/html/dallascorporatemagician.com/wp-admin/custom-header.php on line 391

The site is dallascorporatemagician.com

Any ideas? I tried to rename plugins folder but that didn't allow me to login. Thanks.
