Not receiving emails anymore

 I heard they made some new changes to this website but I don’t know how true that is. I know I haven’t changed a thing on my profile and now for the past five days or so I’m not receiving emails anymore when I make a comment. I checked my profile and my email is still correct. But when I put in my password , It said it was invalid. So I tried to change my password and since I am not receiving any emails, I’m not getting one so I can make the changes. Is anybody else having this problem. It’s just puzzles me that it happened all of a sudden by itself without me doing our thing.
