Website issues fix

I have recently launched a new website (built with Wordpress using Elementor), however have now had two emails from Google Search Console to highlight the following errors:

- Page Indexing Issues detected: Blocked due to access forbidden (403)
- Mobile usability issues detected: Content wider than screen, Text too small to read, Clickable elements too close together

I'm looking for someone to please assist in correcting these areas, along with identifying any other SEO related issues that may need to be resolved to improve overall SEO of the new website.

The website is: www.mindspacefoundation.co.uk

Many thanks,
Tony
