Can't connect when i reset a password

Hello everyone,
Happy new year for all !

I come to you because i have a problem concerning password,
When i use the initial admin password there is no problem, but when i put the new temporary password for a other user, the software ask me to fill new password but i'm block at this step. I give a correct new password but when i click on accept the page reload and ask me one more time to fill a new password. 

I'm using the version 9 of projeqtor on a wamp server.

Thanks for your help, have a good day.

Jonathan
