Account minor problems

When I click on the names in my Notifications , It says that "User does not exist or their account is inactive".

Also the comment reputation doesn't increase and I don't receive up or downvote notifications any more.

And all the account I see are offline, even myself .

I noticed that the "posts made" page in my profile takes a long time to catch up.

Don't worry, everyone has some sort of problem. I also get the "user doesn't exist" notification. I have 11 Notifications stuck, went down from 12, it's just a glitch anyway.

Checked your messages lately? That might be the problem. If not, relog.

Even after relogging, yes, I always check my messages. I get 13 when I get a new message for example, looking at the notifications drops it to 12 and looking at the message makes it 11. I'm rather okay with it since it's not like it adds on and on and on.
