Resolving the “Headers Already Sent” Error in PHP

Occasionally, you might encounter a problem with your website not loading (such as a 500 error). Upon checking the Apache logs, you may come across a PHP Warning that header information cannot be modified because it has already been sent from a specific location in your file directory (/home/user/public_html/php-page.php).

To resolve this issue, ensure that your PHP scripts are uploaded to the server using ASCII encoding, as using formats like UTF-8 can lead to problems. Additionally, verify that the file, such as php-page.php, does not contain any unnecessary characters, including blank spaces at the beginning of the file or unintended output from print or echo statements.
