 * Hi there,
 * i was answering to mraamike topic, but you asked me to wrote a new one. here 
   it is !
 * I have the folowing error and when i deactivate the wp cassify plugin, it disapear.
   Any idea ?
 * 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.
