An active PHP session was detected

Question

I'm running CiviCRM v5.32.2 and the CiviCRM WP REST API v0.1 plugin in Wordpress v5.6.

In Wordpress Site Health Status i get this warning:

An active PHP session was detected

A PHP session was created by a session_start() function call. This interferes with REST API and loopback requests. The session should be closed by session_write_close() before making any HTTP requests.

Do you know if this error is related to CiviCRM, and what to do about it?

Answer 1

The same questions was asked at WordPress Site Health contains critical errors unless CiviCRM is disabled and had some good answers.

Summary:

• Yes CiviCRM is to blame for the notice.
• No - it's not a real problem.
• Plugins exists to suppress the notice.
