I regulary get the fault

Warning: Cannot modify header information - headers already sent by (output started at /usr/home/deb4195/domains/ikf-forum.eu/public_html/inc/languages/english/index.lang.php:1) in /usr/home/deb4195/domains/ikf-forum.eu/public_html/inc/functions.php on line 78

And normaly I can do it by myself but now it wont work.
I add the mod for who was online today, I make some changes with wordpad and then I get this fault.

I checked the functions.php file for empty spaces in the beginning but it is not there. Also the index.lang.php is good.

Your index.lang.php contains weird chars at the beginning. You need to look in a hexeditor if you want to find whitespaces/other crap ... a normal texteditor doesn't display those.

Try using another text editor like Notepad++ or Crimson Editor. Note that you should apply the modification again (using the new program) on the original MyBB file. Redownload it if necessary
