Hi Simon,
I hope you are well today and thank you for your question.
I logged into your website and saw your website home page was broken due to switching the page builder.
Please note that you can only edit the page using the same page builder that you used to create it so if you have used WPBakery or Unyson or Gutenberg or any other page builder then please use the same page builder to edit the page.
Do not switch between page builders or else you will lose the content so choose the page builder that you want to use initially when you create the article content.
I have restored the older version of the page from the revisions.
Best regards,
Shufflehound team
