I have noticed twice an error with version 12.0
I had the option "Do not temporarily cache the AES key" inactive and "Double
click to edit pages/menu" active. I change it to "Do not temporarily cache
the AES key" active and "Double click to edit pages/menu" inactive and saved
the changes. Closed the woas page and reopened it.
I do not know which step is actually doing this... after the changes I
notized that some (latest) changes where gone and some pages had only :
instead of :: in the name.
Just to let you know there is an issue..
