Diablo 1 HD Hellfire Mod | Awake

Hi, this is my first post, first, I found the mod amazing and i love to play it, but i have a question (Hope is not a silly question) When i'm going to do the quest of butcher's chamber i entered the red portal and cleaned the level, but i can't open the doors to the butcher when i put the mouse on the door the text says "BROKEN DOOR" , and i can't access to the small butcher's area and I can't do the quest, can anyone tell me how to do it?

Thank you so much.

SOLVED, i didn't saw the lever in that level, sorry. My fault.

Welcome to the forum. And in the future if you can't figure something out you can also check the docs, i've put in a small description and some pictures to show what's important in each quest.
