when i place a block it doesn't camo but it remain stone, HELP PLSSSS :'((((((

Secretrooms only works without optifine for some reason. I think it has something to do with the way forge and optifine work together. You might need to uninstall optifine or you can try switching to a different older version of forge. I hope this helps ^v^

All you have to do is install an older version of Optifine
