My 1Password 3.8.21 had been working well (used almost daily) with Safari 6.1 on my iMac OSX 10.8.5 when suddenly today it failed with notice of "Problem with database" including truncated instructions that could not be deciphered. I have not made any updates to 1Password, Safari or OSX recently - at least several weeks. 1Password works ok in Firefox. Many of the Agilebits discussions relate to Safari 5.1 or OSX Mavericks or 1Password 4. I'm not using any of those. I did not and do not have Private Browsing turned on. None of the help suggestions I found on Agilebits have been any use. Any suggestions?
