Guild Wars 2

I am the Leader and founder of a guild.
Suddenly since today I can’t represent my own guild, nor access the guild’s storage.
I can represent other guilds, but not my own.

I don’t know if there is a link but I had just bought and used the Commander’s book

Guild: Dragons Of Dark Flame
Server: Crystal Desert

I hope this can be solved fast since a lot of the materials I needed to craft are in the guild’s storage.

Try going out into an explorable area such as Queensdale, Bloodtide Coast, etc, and then try to stand down and represent your guild. I’ve seen this error happen only in towns, but fixes itself when you leave town.
