please can someone advise why I no longer able to edit the page in sites default editor?
I am not sure what you want but edit pages you need download a plugin “elementor” or “king composer” etc
but I add image below you edit as you wish.
Or you need read the documentation the file you already buyer a themes wordpress.
and click button “preview” see your website
there can be few reasons:
- you didn’t install the theme bundle plugins especially the visual editor plugin
- your theme don’t compatible with wordpress5 block editor. if not compatible then you have to install classic editor (free) and then try to edit.
Please check the above points. if you are still facing issues then the best way to get the support is Contact your purchased theme Author. How to Contact Author and let them know because theme Author are best expert about their theme functionality. theme Author will be very happy to assist you.
