Suddenly can't log in to site admin.
I was working with some php code that called tweets--got it working--when weirdness started. I would UPDATE a php file in APPEARANCES/EDITOR in my site admin, and started getting the message:
Warning: Cannot modify header information - headers already sent by (output started at /home/content/s/o/l/soldiersadmin/html/wordpress/wp-content/themes/Cirque/functions.php:22) in /home/content/s/o/l/soldiersadmin/html/wordpress/wp-admin/theme-editor.php on line 75
It was intermittent at first. I tried removing what I had done but started getting message anytime I tried to UPDATE any file. Meanwhile, the site (build version at http://soldierstothesummit.org/wordpress) works fine.
I thought maybe my computer was just sending weird code so rebooted and now get the above message when trying to log in to admin. I can't login now.
