Hi @nickadigital,
My apologies for the late reply.
In the future, please take a look at the Sharing Debugger, it will help you understand how Facebook interprets your website.
It gave me some errors it encountered and cached earlier. Those errors are no longer present and were caused by a hiccup, explained by the following:
Facebook is used by millions of users simultaneously, and their systems have to keep up with all what we share. So, sometimes it can and will have a hiccup where data isn’t parsed correctly.
As you can see in the image below most of the data is fetched correctly. All that’s left to compile is the homepage title and description.

The reason it’s not fetching everything correctly is that another plugin, or the theme, is outputting restitute Open Graph data. Take a look at your source, and you can see that more Open Graph data is outputted from line 45 onwards.
After that has been resolved, you’re safe to publish your site on Facebook once more 🙂
