 * After installing Delhivery Courier Plugin following error appears in my WordPress
   status page
    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. 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)
 * This may be due to error in your plug-in
