HI again,

Didn’t find the solution but I found a workaround.
Once I enter any changes in the front page meta, I first need to hit ‘preview change’ and actually preview the page, then hit ‘edit page’ and update.
Only then the changes are saved. The slider and other issues related to that are fixed, but I still don’t know why it can’t save in the first place.

Cheers
Yann
