I'm having a bug in the Unified Agouros quest i need help

I’m having a bug in the unified omens quest, I’ve already opened a ticket and gm asked me to rename the cache folder within the WOW installation and type a command, after that I still can’t complete this quest, can you help me until Tuesday By Friday the game will have already been updated so I can continue with this mission, and it is weekly, I already abandoned it and picked it up again, I did what was asked of me and it doesn’t work

thanks
