 * I am receiving the following error:
 * 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.
 * After deactivating all plugins and reactivating one by one, the error seems to
   be connected to WP Cassify.
 * Do you have any suggested solutions?
