I've cleared my cooking and old browsing history. Does not help.
I will say my inability to both post and reply to comments on news articles on the MSN web page has nothing to do with my browser. You see I have an iMac, MacBook Air and a Samsung Android cellphone and I'm unable to post or comment from any of these devices and that is why i suspect a block has been placed on my account. MSN needs to be honest about whether on not they have put blocks on accounts. Microsoft should say YES we have imposed a block or NO we have not and stop sending inquiries back to the community for answers.
As a matter of fact I have the latest versions of Safari because I have downloaded the latest version of Apple's operating system Yosemite and on my cell there's no excuse for this problem.
