I saw the same issue posted about 1.5 years ago. Any hope of a fix? Running 1Password v6.0.2, Chrome 48.0.2564.116 (64-bit), 1Password Extension for Chrome 184.108.40.206, OSX 10.11.3
I also tried reporting this issue using the menu "Report Website Issue". When I click on the menu item, a new tab opens in Chrome and I receive a message "Oops, something went wrong" message on the Synapse website.
1Password Version: 6.0.2
Extension Version: 220.127.116.11
OS Version: 10.11.3
