<![CDATA[Opera Beta 40 Mac .. Cannot sign into sync]]>I just installed Mac Beta 40 and noticed that my preferences wasn't showing that I was signed into Sync. I attempted to sign in, entered my userid and password, clicked sign in and nothing. I verified login credentials via web login. Thanks

Cannot sign into sync on Sun, 16 Oct 2016 12:56:47 GMT]]>I have the issue at home: Opera 40 up-to-date running on OS X 10.9, failing to sign in and sync. It has been broken since July 2016 or earlier.
The opera://sync-internals page reports an unrecoverable error (BackendInitialize failure), which seems related to the Chrome engine. Maybe the local data have been corrupted in some way, however I don't know how to repair that.

Checking on <sync.opera.com/web/>, remote data are OK. At work I use Opera 40 running on Win7, and this one signs in and syncs alright.

If I sign in with a wrong password, I get the same error as a correct password - "An Error has Occurred .. Please try again", Perhaps detailing what the error is would be beneficial.

Thanks

@rlh1533 - I have no issues signing into sync with v39 .. Did you try to log into the web site "auth.opera.com" or "sync.opera.com" to verify your login credentials?

I just downloaded Opera 39 on the Mac and have no issue signing into sync. So it's something related to the v40 beta

Then I thought that it was a special character in my password (contained '{'), so I changed my password to remove special characters and still not able to sign in. Weird .. I'm going to delete my login and in 7 days will attempt to create it .. We'll see how that goes.

Found this on the Developer v40 change log from July .. I didn't see it in the Beta v40 change log .. Could this be the cause?

It shouldn't cause any issues.
