Static home page “frozen”
I am experiencing a strange problem with my static homepage. It is "frozen", which means it cannot be changed, or replaced, and does not show any new blog posts or new widgets. All other blog posts and pages work fine.
What is really strange: You can make changes when you switch on the customizer, but I am not able to save anything. Tried to deactivate all plugins, clear cache, disconnect CDN etc. – nothing worked. Tried to set a new static homepage, too – it does not change anything.
