 * Hi, Guido!
   I’m experiencing critical errors after updating the VS Contact Form
   plugin to version 18.7. I’ve tested this and downgrading to version 18.6 resolves
   these issues.‘Site Health’ shows two critical errors:**Active PHP session detected**
   The PHP session was created by calling `session_start()`. This prevents the REST
   API and loopback requests from working. The session must be closed with `session_write_close()`
   before making any HTTP requests.**The REST API returned an error**REST API is
   one of the ways WordPress and other applications communicate with the server.
   For example, the block editor screen uses it to display and save your posts and
   pages.An error occurred while testing the REST API:REST API endpoint: `https://
   mysite.com/wp-json/wp/v2/types/post?context=edit`REST API response: `(http_request_failed)
   cURL error 28: Operation timed out after 10002 milliseconds with 0 bytes received`
   Rolling back your plugin from version 18.7 to version 18.6 fixes these errors.
   Please check this. I’ll wait for the plugin update. I’m currently using version
   18.6.

 * Thank you so much, Guido! You’re a wonderful person. You work very quickly. VS
