I want to inform you, that I got today a strange behavior from our website.
In the hardening options of the WAF I have one user as be "protected".
Strange: Today this user was blocked. I got no information about the blocking per mail as I usually get (I monitor all blockings).
After I unblock the IP adress of this user (asked per telephone) the problem was solved.
Perhaps you can have a look about this strange behavior at your servers.
I want to tell you about this because I had never problems with the AdminTool and be very satisfied with the software. Perhaps this hint helps if there is really a bug in the actual version.
