Can't login to forums with Opera 12.16 on XP anymore?
I thought I was in a bad dream. Are others having this problem? I cannot believe they would do this. I use Chrome and it works perfectly. I hate Chrome based browsers.
If anyone did anything its the maker of the website, not Opera. It is possible that you have a damaged cookie though. Try deleting all of the cookies you have for the offending website and the forum software it uses and see if that helps.
Opera forums presented a bug some days ago and was inaccessible by any browser so try clearing your cookies.
There's a new version 12.18 that resolves some security issues around security certificates/protocols. It's a good idea to update too.
