Safe Headers Scanner
·
Scan themes and plugins for potential header issues such as whitespace before/after PHP tags or direct output before headers.
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 <?php tags
* Extra whitespace after closing ?> tags
* Direct output (e.g., echo, print) before headers are sent
Results are displayed in a clear report, so you can review and fix potential issues easily.
