When i check the WordPress ‘Site Health’ tool, I’m presented with the following two error messages, and i can’t get rid of that issue :

* 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 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)

Upon debugging by deactivating plugins, when deactivating “Tulsi Theme” both of the errors disappeared.

How could i fix this please HELP ??

Any help with this would be thoroughly appreciated, many thanks for your time..
