CrackingGears

I've tried changing my difficulty in my server but it doesn't work, then I found out that it was hardcore setting I enabled. I turned it off, made it peaceful and there was still tons of mobs and the hardcore hearts. The hardcore setting in minehut isn't working. I've researched more about it to see if more people have the same problem, and they did but, people didn't give a proper answer. Is there anyone that know how to fix this?
