I used the in-game server settings after making myself Admin.
Everything other in-game server setting works the way that it is configured. Such at PvP attack buildings time restriction.
I will have to check the in-game server settings again to see if I misunderstood how they are configured.
I tried the link you posted, but was not able to check it. I do not see any server settings on the GPortal website to allows configuring the Purge or any other game setting for PvP.
What is the difference between the following?
PurgeRestrictionWeekdayStart
PurgeTimeWeekdayStart
My current setting can be found here. I did go into through GPortal website, took the server offline and set up the missing times, but I am still not sure if this is correct and will work as currently configured.
