Cannot modify header information
Posted by , Last modified by David Suker on 21 November 2019 03:32 PM

One of the more common problems that is the result of a whitespace at the end of a file.

The error looks like this:

Warning: Cannot modify header information – headers already sent by (output started at /home/user/public_html/config.php:40) in /home/user/public_html/index.php on line 6

In order to sort it, remove any extra lines from the file specified in the particular error message.
