i have wanted to change my password to something more secure, but when i access the page
http://boincstats.com/en/bam/account/
I can't seem to change my password.

I have tried entering my old password into the boxes, and entering a new one, but it doesn't update my login info.

I have managed to recreate my issue on both opera and chrome.

Any ideas to solve the problem?

Your probably doing this but make sure you put the new password in both Box's & then click on Save ... It should work if you do that, be aware that if you use BAM & you change your Password here at BoincStats it will change your password at the Projects too, at least I think it will anyay.

I have tried this, but it still doesn't change my password.

Willy will probably have to check into it when he gets time ...

The odd thing is, I then tried to logout and log back in and now none of my passwords work [the old or the new one].
I had to get a password reset e-mail sent to me.

LonMcGregor, I don't know if you solved this issue, but I was having the same one and found that the password field does not seem to like special characters. I used a new password without special characters and followed the process Ste/e outlined below and was able to update my password.
