Nostalrius Begins - Quality wow vanilla realm (1.12)

I recently left my guild to help someone get signatures to make a guild. Now I can't get back into my old guild. I get the request to join and hit accept and then nothing happens.

I have tried:
/gquit,
relogging,
fulling exiting game,
clearing WDB and WTF folders.

I don't know what else to do. Any help please?

Can you join any guild at all? Or just not your old guild?

Maybe there was 321 people in your guild, you left, and those jerky guildmates of yours immediately filled your spot.
