What is wrong with Mibba?

I've been trying for two days to delete some chapters to my stories and it keeps coming up with be right back (BRB)?

(And the chapters are not deleted when I check) Is with happening with any of you guys?

It's frustrating becasue I'm tyring to revise (re-write) my story and I can't because Mibba won't let me delete my chapters. Do guys know what is going on? And when most likely this will be over?

I've been on this site for almost two years now and it's never happened to me before. So now I'm like wtf?

So can you guys help me?
