When removing (accidentally) blocked devices, I get this error. When I attempt to remove a forwarded port, I get this error. Half the time I try to do anything with my business gateway, I get that error. It has been going on for a couple of months -- I've noticed a lot of other people on the forums with the same error -- was a fix for this ever released or discovered? I saw an attempted work around, but that didn't work for me unfortunately.
