WotLK wow error 134 , help!

I need help on what to do with the wow error 134, I've been with the error for a week I try to clear the cache but after two days it stops working, I download the game again without any texture pack and the next day the error returns, What should I do before? I used to play with a legion texture pack that worked well for me, I played with that pack since February and it never gave me problems, but for 1 week it has been impossible for me to play without it always jumping wow 134 every 15 minutes it jumps it doesn't matter where it is, it may come out that an error has occurred because it did not charge a hairstyle or something and not what to do now
