    I am a relative beginner at WP & really need help as I appear to now be locked out as I get this error message when trying to login into wp-admin and can get no further. I dont have the cpanel login details either unfortuntely.

    Not sure exactly when the problem occurred, but having gone though a standard update to the latest version of WordPress (v 3.5.1) I seemed, as a result, to get all sorts of things not working that I had not consciously touched. For ex. WPML language widget simply disappeared and although I managed to put it back I need to change the format. To fix these I was trying to get some code for the WPML plugin to work in the functions.php file and now I get this error message:

    Cannot modify header information – headers already sent by…(output started at /homez.386/marcomou/www/wp-content/themes/marcom/functions.php:288) in /homez.386/marcomou/www/wp-includes/pluggable.php on line 876 `
    How can I proceed?

    Do you have a back-up copy of the site files? If so, you can use FTP (or other file manager) to replace the messed up functions.php file with an older copy.

    OK thanks that is helpful, but personally no I don’t – I’d have to go to the hoster for it. Also I use MAC so I guess cyberduck would be my option to do this? This is a friends site that I was helping out on – ouch, wish I hadn’t touched it!

    Yes, Cyberduck is fine – though FileZilla has a Mac version as well. I’m assuming (from the name) that’s a custom theme – if not, you can download the original theme to your local computer and use the unmodified functions.php file from there. You can usually see more info about the theme in the style.css file (there’s generally a commented header section at the top of that file).

    You can also probably regain access to the site by renaming the theme folder (again via FTP) – WordPress will default to the twentytwelve theme (assuming it’s in the themes folder) – and allow you to login. But you’ll still need to sort out what the problem is in the functions.php file :(.
