You have extra space at the beginning and or end of your language file listed in the error.

I had a 'cannot modify header information' error message and found the fix -- and updated the Wiki -- woo-hoo -- I get to help the next person searching for the " Cannot modify header information " error in the forum.

Ok, I have been a newby too long and am just glad to be actually contributing... LOL

You may also get this message if you 'checked out' files, edited, then uploaded with Dreamweaver, and did not 'check in' the files. If you 'check in' the files via Dreamweaver the error will disappear.

I'm having the exact same problem posted here:

Warning: Cannot modify header information - headers already sent by (output started at /home/stunmast/public_html/includes/languages/english/stunmasters/meta_tags.php:1) in /home/stunmast/public_html/includes/init_includes/overrides/init_templates.php on line 78

I searched the meta_tags.php file but can not find any blank spaces either at the beginning or at the end of the file.

I'm also getting these characters thrown on my pages: 
Anybody know what they mean?

1. /includes/languages/english/stunmasters/meta_tags.php:1 ... line #1 ... is either blank, or has a preceeding space on it.... on the server.

2. the odd characters you mention are likely file-corruption. Perhaps you need to download a copy of everything on your server and compare it with your working files to see which files may need to be refreshed with good copies?

I have this same problem but I don´t know exactly what I have to do, I dont see any extra space before the line.

Warning: Cannot modify header information - headers already sent by (output started at D:\inetpub\paco-site\portal\includes\functions\functions_email.php:347) in D:\inetpub\paco-site\portal\includes\functions\functions_general.php on line 41

The lines 345-350:

    //DEBUG -- to display preview on-screen
    if (EMAIL_SYSTEM_DEBUG=='on') echo $file_holder;
    return $file_holder;
  }

what do I have to change? =( thanks for your help

You might want to make sure you do not have duplicate files on your server, that was my problem. I'm using an FTP program to upload my files. At one instance I did not make sure I was uploading to the proper folder. In my case the warning message was referring to:
/includes/languages/english/stunmasters/meta_tags.php

but I had a duplicate file on /public html/languages/english/stunmasters/meta_tags.php.

Once I deleted all the duplicate files I had no other problems. Hope that helps...
