Hi,
I tried again on your site to create a draft post and a draft page, but couldn’t replicate once more.
Also tried to refresh existing pages and still the same.
I tried also in my flexform installation on my dev server and it worked has expected.
I don’t doubt you but without replicating it I can’t debug it.
If there is a specific page where it’s happening that when you load it let me know the url and don’t change anything so I can debug it in the same conditions.
Thanks
