<![CDATA[Google cookie mismatch]]>Hello,

I have been trying to access my gmail account with Opera, and Google keeps returning a "Cookie Mismatch" error message, saying they have "detected a problem with your cookie settings". My browser privacy is set to "allow local data to be set" and I have already added 'www.google.com' to the list of HTML exception sites. I would try to email Google, however I currently don't have access to my account any idea what could be causing the mismatch?

I deleted all google cookies and my browsing history.
(google sites worked well in my opera for mac browser until last week)
I can now access any google sites. Instead I get the mistmatched cookies error message.

Ugh, this is frustrating. I'm thinking on moving back to firefox, at least I never had that issue when trying to access gmail. 😕

Going to Preferences | Privacy and Security | Cookies | Click 'All cookies and site data' and delete any google/gmail cookies should sort it out.

Once you've deleted any google cookies, logging into gmail should create a new one that works properly.

I don't use Gmail myself, but you'd need cookies for the actual mail site at least. Maybe use *.google.com and the Gmail site…
