Understanding the Error:
To effectively fix the "WordPress Cannot Modify Header Information" error, it's essential to understand its origins. This error typically occurs when code tries to modify HTTP header information after it has already been sent to the browser.

Identifying the Culprits:
Pinpointing the exact cause of the error is crucial for successful troubleshooting.

Checking File Permissions:
Incorrect file permissions can also trigger the error. Ensure that all files and directories within your WordPress installation have the correct permissions.
