At the time of this article, I was running Google Chrome web browser Version 39.0.2171.95 (64-bit). Everything was working fine until one day I closed the browser then reopened it too quickly and got an error about my profile being inaccessable. From that point forward, no web site would prompt me to save my password. And my entire password list appeared to be blank.
Needless to say, this was very frustrating. The user names were still there and would populate the login forms for sites I had already stored my password for. But the passwords would always come up blank.
Going into settings->advanced->manage passwords showed two blank lists where I use to have entries.
I tried all of the other things I could find on the Internet and none of them worked. I still had Firefox installed and most of my passwords were stored there so I tried importing the passwords again. That simply caused Chrome to crash and did not solve my problem.
After a very long day of searching and trying everything, I finally got it working using these steps...
If you start having trouble again after you perform steps 8-10, simply delete the google-chrome folder again and restart the browser. Things should start working. You will need to start building your password collection again. But in my case, once I performed steps 8-10, everything worked fine and my passwords were all restored and working.
Hope this helps!
