Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello,

When I am playing on the PVP realm, and join the LFG Channel, I can join the channel but am unable to talk in it. When I play on PVE realm, it works fine. I have tried exiting the channel and re-joining, restarting client, etc and nothing seems to work. Any help with this issue please?

Thank you

Got the same problem with the /world channel.
It only works if I /leave world an after that I /join world again.
After that, Im able to write in the world channel.

Im doing this with an simple macro.

Guess there are any smarter solution, but I dont know them as well.

Greetings
