Getting error: "Unable to communicate with server. Saving is not possible at the moment"
Asked by Maximilian W?rth:

It is not possible to edit existing pages without getting this error message "Unable to communicate with server. Saving is not possible at the moment."

I already turned off collaborative editing and it doesnt matter which character or symbol i use. I also rebooted all services and the operating system.

Is there anything else i could try?
