    I’m posting this here as I can’t remember which version of ModX I have installed, and I can’t log in to check. It’s a 9.x version.

    I haven’t logged into my manager for over a year, and I haven’t made any changes to any files as far as I know. When I tried to log into the manager today I got the following error on the login page:

    Warning: Cannot modify header information - headers already sent by (output started at /nfs/c01/h12/mnt/33105/domains/neilcreek.com/html/manager/includes/config.inc.php:1) in /nfs/c01/h12/mnt/33105/domains/neilcreek.com/html/manager/index.php on line 148

    Attempting to log in via the form which appears as normal below the code also gives the following error in a system dialog:

    Is it possible my host has made some changes to the site settings that could have caused this?

    Would it be prudent to install Revolution 2.0 on top of this existing site to fix the problem, or would that risk data loss?

    You can see the error yourself at: http://www.neilcreek.com/manager/
    I’m seeing the problem in Firefox v 3.6.8, MSIE 8.0.7600 and Chrome 5.0.375.126

    Is there anything else you need to know to help me diagnose the problem?

    Thanks in advance for your help!
    • You really should probably upgrade. I think you’re right in deducing your host has done the same.

        Would an upgrade over the top of the existing installation be safe for the existing web site?
        • First archive your entire site. Then try to upgrade a copy of it in a subdirectory on a fresh install, that makes sure all legacy snippet code is not involved. If that succeeds, rinse-and-repeat for the base site, or move the one in the subfolder to the root after removing everything. Details are covered at http://rtfm.modx.com
