Headers already sent – error

    I was attempting to add code to functions.php in the wp-includes folder to fix pricing problems with Woocommerce, bulk discounts and options. So I added the php at the end of that file and immediately broke something. There were several errors in the admin page and website. So I removed the code and revert the functions.php file back to its original state. But the errors persisted. I saw several pertaining to this plugin so I deactivated it and then ended up deleting it. Most errors are gone but the following error is still on the admin side.

    Warning: Cannot modify header information – headers already sent by (output started at /homepages/8/d95069775/htdocs/mysite/wp-includes/functions.php:1) in /homepages/8/d95069775/htdocs/mysite/wp-admin/includes/misc.php on line 1198

    I confirmed that both these files are identical to those in a fresh wordpress install.

    Strangest thing, even though the content in the files were identical, somehow the files were different. Yes, I check for a space at the end. But I decided to replace the file on the server with a “fresh” file from a downloaded wordpress package and the problem is resolved. Somehow the text file encoding is different.

    Reinstall WordPress and never ever edit its files. Use the functions.php file in your active theme folder instead. If no such file there, create it.

    Thanks. Using the “Code Snippet” plugin now.

    That’s is the right way too.
