Hi I have got a problem I was installing some plugins and after deleting them the mybb show error:

Warning [2] Cannot modify header information - headers already sent by (output started at /var/www/vhosts/pgc-cs.eu/httpdocs/index.php:1) - Line: 1542 - File: inc/functions.php PHP 5.2.8-1hardy~ppa1 (Linux)

header($cookie, false); 

-> line from functions

What should I fix to make it work good?

Sorry for english but I worte it very quickly.

Did you manually edit one or more .php files with Notepad?

Yes, I do.

But I have go proble when I replace my index.php with oryginal index.php the subforums are not working.

Make any edits that you need to make with a text editor other than Notepad. Use Wordpad, Notepad++, Notepad2, etc.

So, download the original files and then make the changes you need to with another text editor.
