I get an error that says:
Problem loading 1Password data file
A key data file could not be loaded and 1PasswordAnywhere cannot continue without it.
Please see this help guide for troubleshooting tips.
This appears to have been a recurring error over the last year or so, I can see numerous threads where it was resolved only to recur again. The last thread is here: https://discussions.agilebits.com/discussion/48454/1passwordanywhere-not-working-with-dropbox-resolved-usage-issues-with-chrome-45-firefox-41
It opens in Safari so it's a Chrome-specific error. Opening the file in an incognito window without extensions doesn't help.
1Password Version: 6.0.2
Extension Version: Not Provided
OS Version: 10.11.3
Sync Type: Dropbox
