ActivePHP Session detected causing API loopback requests

Hello,

A site health warning “Performance” was noted on my website which is caused by the multi currency plugin. I disabled all site plugins one by one and checked to see which one caused the PHP call to appear and disappear, and your plugin is the culprit.

Below is the error detail:

An active PHP session was created – Performance (Site health)
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.

Can you please advise how to address this issue?

Site access can be provided on request.

Regards
George
