    Hi,
    I’ve been through the pages here, I’ve searched, I’ve checked for blank lines (there were none). This is on a site that hasn’t had anyone in the back end or file system for months yet the error suddenly appeared.

    Warning: Cannot modify header information – headers already sent by (output started at /home/hhenxxxx/public_html/coomarodeo.org.au/wp-includes/category.php:1) in /home/henxxxx/public_html/coomarodeo.org.au/wp-login.php on line 349

    Give this a read and check your wp-config.php file.

    Thanks,
    I did read that thread and checked config.php
    No extra spaces or lines I could find. It didn’t end in ?> but I added that, no change to errors.

    It’s difficult to find as it’s white space. I mean, if there was a red arrow pointing to the spot what fun would that be? 😉

    Try this. Make a backup copy of your existing wp-config.php file. Call it wp-config-save.php.

    Now with that backup safely made, copy the wp-config-sample.php on top of your existing wp-config.php (you did make that backup copy, right?)

    Now carefully edit the new wp-config.php file in notepadd++ or the favorite editor of your choice and put in your details for

    define('DB_NAME', 'yourdbname');
define('DB_USER', 'yourdbuserid');
define('DB_PASSWORD', 'yougettheidea');
define('DB_HOST', 'yourhost');

    Save that and see if that does it.

    If that doesn’t work, try this.

    – resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

    Thanks again Jan,
    I’ve disabled plugins by renaming folder, and I’d already replaced wp-config and got same errors :/

    interestingly coomarodeo.org.au works, http://www.coomarodeo.org.au does not, and wp-login is partially screwed to start with, totally screwed once I try to log in

    It can also be a theme issue. Try moving your current theme directory out of the wp-content/themes directory.

    If that’s it then when you visit the dashboard URL you should get switched to the Twenty Eleven theme.

    moved weaver out of /themes, result was a blank page when I tried to get to main page, or same error from wp-admin.

    if it was one of my main sites I’d have backups and all, but I just host this one as a favour and now stuck trying to fix it for them 🙁

    Try uploading a fresh install of WordPress.

    Download the zip archive and upload everything except the wp-content directory.

    Hi,
    this evening I’ve found something more disturbing… I have 7 wordpress sites, all different domains, all on the same hosting provider and they ALL have the same problem. Few different versions too.

    🙁

    None of them work? You may be hacked or perhaps your host has done something bone headed.

    Can you share a link to one of them?

    yes that’s what I suspect – I’ve logged a help request.

    http://www.relaxedhorsemanship.com/
    http://relaxedhorsemanship.com/wp-login.php and if you try to log in, many more errors and no login.

    I’ll let you know what web hosts say when they get back to me

    got reply…

    I do apologize for the inconvenience. I have reinstalled the core files of all the affected WordPress sites that you had mentioned and this action has resolved the issue of http://www.domain.com showing an error message. If you have any additional questions or concerns, please do not hesitate to contact HostGator Support for further assistance.

    Best Wishes,

    and yup, fixed.

    Thanks heaps for your help last night, I really appreciate it.

    Glad you got it sorted out. 😉

    If you haven’t done so already, you may want to backup all of the files and databases for your WordPress installations.

    http://codex.ww.wp.xz.cn/Backing_Up_Your_Database
    http://codex.ww.wp.xz.cn/Restoring_Your_Database_From_Backup

    Your installations are valuable and off server full backups are the best safety net you can have.

    Once you’re comfortable with your setup and have reviewed the master list, try upgrading to 3.4 to bring those sites up to date.
