If a configuration variable is locked at an upper level, E.G. Site, using %lock
And one needs to un-lock it at a lower level to reset it for a specific project "HOW" There isn't an %unlock and %undef does not work either.
The only way to unlock a variable is to go into the configuration file it is locked in (through Notepad) and take the %lock out from in front of the variable it is locking.
