 * Captain Form is throwing two critical errors on my website:
 * An active PHP session was detected Performance
 * 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. The REST API encountered an error Performance
 * The REST API is one way that WordPress and other applications communicate with
   the server. For example, the block editor screen relies on the REST API to display
   and save your posts and pages.
 * When testing the REST API, an error was encountered:
 * REST API Endpoint: [https://staging3.*******.co.uk/wp-json/wp/v2/types/post?context=edit](https://staging3.*******.co.uk/wp-json/wp/v2/types/post?context=edit)
   
   REST API Response: (http_request_failed) cURL error 28: Operation timed out after
   10001 milliseconds with 0 bytes receivedPlease advise ASAP.
