Headers are essential components of a website, responsible for transmitting important information between the server and the browser. However, sometimes WordPress encounters a common error that states, "Cannot Modify Header Information - Headers Already Sent." To understand how this error occurs, let's explore its causes.

1. Whitespace or Characters before the Opening <?php Tag:

One common mistake that triggers this error is including whitespace or characters before the opening <?php tag in files like wp-config.php. These extraneous characters are sent to the browser, disrupting the header information.

2. Inappropriate Encoding:

Improper encoding of files, such as saving them with UTF-8-BOM, can lead to the "Cannot Modify Header Information" error. It's crucial to ensure that files within your WordPress installation are encoded correctly.

3. Plugin or Theme Conflicts:

Conflicts between plugins or themes can also result in this error. Sometimes, a particular plugin or theme may mistakenly send header info, creating conflicts with other components.

To resolve this error, follow these step-by-step troubleshooting techniques:

1. Check for Whitespace or Characters:

Inspect the files mentioned in the error message, like wp-config.php, and ensure there is no whitespace or characters before the opening <?php tag. Remove any unnecessary space, line breaks, or characters in those files.

2. Review File Encoding:

Validate that all files within your WordPress installation, including themes and plugins, use appropriate encoding such as UTF-8 without BOM. Convert any files with incorrect encoding to the correct format.

3. Temporarily Disable Plugins and Themes:

Disable all plugins and switch to a default WordPress theme to identify if a conflict exists. Enable each plugin one by one and test after each activation to pinpoint the conflicting plugin. Similarly, switch themes to determine if a specific theme is to blame.
