MacOS Sierra Version 10.12.6
Opera Version 46.0.2597.57
1Password Version 6.8 (680014)
Note: I've updated three other Macs so I'm going to have a long day ahead if this breaks 1Password. I'm holding off updating my iMac until it works and will tell the rest of my family to do the same.
Note2: When you save a draft in this forum board, you can not post it later as it won't let you choose the category and then errors out saying you have not chosen a category.
So, on to the error:
I was just notified by Apple that there was an update available to both 1Password as well as OS X.
I updated and allowed it to install everything and reboot.
Now 1Password errors out when trying to open Opera with "1Password can't save or fill in Opera"
I've added the ~/Library/Application\ Support/Chrome
Still get the error.
I added (touch) a file inside the Chrome directory just to make sure I could write to it and that worked.
I can no longer use 1Password in Opera on this machine.
I did have an entire writeup about Safari as well but while I was writing it I got the "Compare this number with the one in 1Password" and the extension is now working in Safari.
Here are screenshots of trying to make Opera work with the new version of 1Password
