I can't modify the information for the users. Especially the passwords. I noticed I couldn't access any files through the SMB because it didn't let me use my user account saying I have incorrect password. On the webgui, I could see that all the user accounts didn't have any password the password was all empty. So, I tried to assign passwords to the accounts, but it doesn't change. It looked like I am having very similar problem as this person. As soon as I changed the password, it becomes null. It looks like it forgets, or the password get corrupted. I tried things like change web browsers, turning the server on and off and trying to make new account. All of them didn't work. Any idea to solve this problem?
