Error: Headers already sent

  • 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.

    I have been staring at that page and troubleshooting various for the better part of an hour before posting here. I mentioned above that I checked both wp-config and the pluggable files and I see no blank spaces.

    The issues could be in any one or more of your theme’s template files – especially functions.php – or in any one of your plugins. Try:
    – switching to the default theme by renaming your current theme’s folder using FTP or whatever file management application your host provides)

    – resetting the plugins folder by FTP or phpMyAdmin.

    I hate to mess with phpmyadmin. I don’t have a clue what I am doing and my back end person is out with a family emergency.

    If I overwrite functions.php with a clean file from a fresh install, does that pose a problem? I have two plugins that I added 2 days ago. The site was working this morning so I don’t think it’s either of those.

    What is dataquery.php and where did it come from?
