 * I have 3 critical issues on my WP. Tested with deactivating plugins one by one
   and the problem is the plugin Hide Price Until Login. I saw many tickets about
   this problem from year ago, but the problem is never solved. So this is a request
   to update the plugin and solved this problem.
 * Issue 1: 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.
 * Issue 2: 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)
 * Issue 3: Loopback requests are used to run scheduled events, and are also used
   by the built-in editors for themes and plugins to verify code stability.
 * The loopback request to your site failed, this means features relying on them
   are not currently working as expected.
