[resolved] New users can't log in. (new password hash problem)
Hello/Hi/Greetings,
Have not created new users in a while, but today needed to and can't. I mean I can create a user, but he can't log in. Gives error "Invalid username or password!" even with the simplest password.
Old users can still log in luckily.

Re: [resolved] New users can't log in. (new password hash problem)
Troubleshooted a bit. Went into MYSQL.
New user is created indeed. However something is wrong with password hash generation now since one of the last updates?
New user has password hash, yes, but can't log in with the set password.
When I copied my own old user password hash in mysql to new user password hash, i was able to log in with the new user (and my password)!
However I would really like to set a new password for the new user... so any trick to manually generate working hashes from passwords that are able to log in until this gets fixed?

Ensure that the stored password hash starts with $P$, if it doesn't then some other hashing algorithm was used than the portable one of include/passwordhash.class.php
See [Forum, post 181215 by erAck in topic 31381] Lost password and see if its generated password hash works.
Apart from that, you should upgrade from your PHP 7.1.33 that is outdated and EOL for years, use PHP 8.1

Re: [resolved] New users can't log in. (new password hash problem)
Thank you very much. Password hash generated this way and inserted manually to MySQL works.
(the original problematic non working passwords/hashes looked also legit, starting with $P$G like the rest of them.)
More mysterious is that now tested to create another 2 users and those worked instantly. Also changing the password from admin.php UI worked. Like ... it should have all along.
Now the question remains, why creating new user and changing password in admin.php UI did not work for a while there (almost half a day) and then started to work again "by itself". In 2 different servers (test and live) - failed for several hours and then started to work in both now. What is happening?

We don't know what's wrong with your outdated system(s)..
