In an attempt to fix the issue with "Error: Incorrect Version value has been sent." I've tried removing 1Password X from my Chromium 67.0.3396.62 (running on Ubuntu 16.04) and reinstalling it back.
I first installed the beta release (1.8.4), and at first it looked OK: I entered the credentials and saw the welcome page. But then upon clicking the 1Password icon in the toolbar instead of opening the drop-down menu it opened a tab with the same welcome page. Restarting Chromium only moves me back to "Log in to 1Password state" and then it behaves the same: no drop-down menu, only welcome page is shown.
I then removed the beta release and installed the usual one (1.7.3) only to find out that it would behave the same.
I still can log in to the vault via Web UI and use the passwords from there. 1Password extension even detects the log in and asks if I should add the account, to which I answer yes, but with the same result. Basically, I can no longer use autocompletion or password generation features.
Any advice on how to troubleshoot and fix this?
