Hello, Petko-

I haven't tried updating to 2.2.108 yet, but I will be doing that shortly.

To answer your questions:

1. Yes, I can log in.
2. I don't know the users' passwords, but I doubt that very short ones 
3. It's quite likely that some of them were created by very old PHP 
versions, but none was migrated from a different operating system.

I notice that some of the encrypted passwords are much shorter than 
others, e.g.


Am I going to have to write to all of my users to ask them to test 
whether they can log in or not? Does the encrypted password length offer 
any clue as to whom I should be writing?
