 * Hi, first of all, I want you to know that I deactivated all the other plugins,
   and the only plugin activated was iFly Chat. In fact, this is the way I noticed
   that this is the plugin which cause the issue.
 * I have 2 performance errors:
 * 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.
 * And the second one:
 * The REST API is one way WordPress, and other applications, communicate with the
   server. One example is the block editor screen, which relies on this to display,
   and save, your posts and pages.
 * The REST API request failed due to an error.
    Error: cURL error 28: Operation
   timed out after 10001 milliseconds with 0 bytes received (http_request_failed)
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fperformance-errors%2F%3Foutput_format%3Dmd&locale=en_US)
