Safe Headers Scanner helps WordPress administrators identify common issues that may cause header-related problems. 
The plugin scans installed themes and plugins for: 
* Unnecessary whitespace before <code><?php</code> tags 
* Extra whitespace after closing <code>?></code> tags 
* Direct output (e.g., <code>echo</code>, <code>print</code>) before headers are sent
Results are displayed in a clear report, so you can review and fix potential issues easily.

Safe Headers Scanner

Scan themes and plugins for potential header issues such as whitespace before/after PHP tags or direct output before headers.
