Yes frustratingly, basically select a homepage from the dropdown, hit save, and it simply refreshes, with latest posts as homepage… (“wordpresses default home”)
I changed the theme to twenty fifteen and it gets the same error, Which would suggest it’s a WordPress error, and not linked to your theme…
However, as it was working yesterday before the work was done, to solve the above issue with woo commerce bookings… I’m not sure where to start with fixing…
As I don’t know what work was done yesterday by your team to fix the first issue… if that makes sense.
This new WordPress update is an absolute nightmare.
It shouldn’t be affecting setting a homepage though.
