No, wasn’t on overflow. Also, I noticed, two of my characters can’t represent any guild, my third character can represent any guild and can access guild warehouse without problem. I haven’t checked rest of my characters.
Edit: I just tried something, first stand down from the guild, then go to Hoelbrak (use this waypoint: Eastern Watchpost Waypoint), try represent, if it doesn’t allow, then use the portal next to you, that takes you to the Wayfarer foothills (low lvl map) and then click represent. This way I was able to fix it, and it fixed the same problem for my boyfriend.
I had the same problem and your solution worked thanks
