Hello, I am trying to resolve an issue I am having with my installation. Earlier today I was able to get into my wordpress backend just fine. This afternoon, no such luck. I am getting the following error when I try to login:
'Warning: Cannot modify header information - headers already sent by (output started at /home/nsync908/public_html/stillnsync/dataquery.php:1) in /home/nsync908/public_html/stillnsync/wp-includes/pluggable.php on line 890'
I've done some research and have checked out wp-config.php and pluggable.php and I don't see any extra spaces or anything. I don't know much more about how to decipher this problem to figure out the issue. I'm not up on php at all and I don't know where to find line 890.
Any help would be greatly appreciated.
