 * A PHP session is created by a session_start() function call. This interferes 
   with the REST API and loopback requests. The session must be closed by session_write_close()
   before HTTP requests are made.
 * Where do I have to go to to fix that

 * This is often caused by plugins. Deactivate all of them as a test. Does the message
   no longer appear? Then activate them bit by bit until the message comes back –
   then you have found the guilty plugin.
