Cannot Modify Header Error

    Just began getting a “Warning: Cannot modify header” error when trying to upload pictures in the write post panel.
    Have not made any recent upgrades and had been running smoothely for a long time.

    The specific error reads as follows
    The upload file could not be moved to
    /home/xxxx/public_html/wp-content/uploads/2007/12
    Warning Cannot modify header
    information – headers already sent by *output
    started at
    /home/xxxx/public_html/wp-admin/admin-functions.php:1879
    in
    /home/xxxx/pubilc_html/wp-includes/functions.php
    on line 1219

    I understand the usual cause is an extra space in the admin-functions.php code. I checked that found nothing. I held delete and rewrote the ?> closing tag just in case but that did nothing.

    I checked server permissions for all the files and they were set to allow access to write to the folder, so all good there.

    I also note that the listed problem is on a line 1879 that does not exist.

    My webhost crashed the server recently and I am guessing some files got corrupted. Oddly, however, things were working fine in the interim period since.

    My next idea is to try and put in a clean admin-functions.php file just in case that got corrupted. Won’t get to try that until tomorrow.

    If anyone has ideas or has experienced this before would appreciate any insights. I saw a lot of posts in the forum for similar errors but nothing so far seems to provide a solution that will work for me.

    thanks

    note: i’m running 2.1.2. I plan to upgrade but have to test plugins and make theme adjustments before i can do that safely. Haven’t wanted to mess with a solid installation that’s running well…even if 2.3 adds a lot of value.

    The problem appears to be on line 1879 of admin-functions.php . See this FAQ for more info.

    macmanx, thanks for the note. As noted in the post, I read the same faq and tried that. Also, there is no line 1879 in admin-functions.php

    For those encountering this problem in the future – if you recently did server work, or your web host made changes, check that configuration and access permissions weren’t altered during the process.

    My efforts to fix this problem on my own weren’t working. I contacted my hosting provider and found they had accidentally altered some of the access provisions and I was unable to change them myself. A few corrections on their part and all was fixed.
