That way should work, you don't need to reset the password, just deleting the lockout on your account should suffice, refresh your cache, or try a different browser (use incognito mode in your current browser) and test the existing password again.
(empty list or set) would lead me to believe that that field is empty. Which means you're no longer locked out. Unless you're somehow connecting to a different database than what is set in your config.json. (By default, 0)
@zenkamal @a_5mith This sounds like it's due the new way we store post bookmarks.
Before, we stored the pid (e.g. 2341)
Now, we store the post index (e.g. 5)
The bookmark only updates if the current post # is > than the bookmarked post #
Unfortunately, 5 will never be greater than 2341, so the bookmark never goes away.
The old bookmark is basically trying to load the 2341th post in the topic, which doesn't exist. You can clear the bookmark by clicking the "x" at the top right of the notification alert, then that topic should be fixed.
