We have been having issues lately because of problems on Google’s end with Blogger and Google Friend Connect. Some of you cannot enter giveaways, some of you cannot log into GFC.
I found some info on the google help desk. you can try these to log into blogger and see if it helps.

Also you must dump all internet cookies and temp files! the cookies were corrupted from their updates/crashes last week.
Also, if you can post to enter, but cannot follow via GFC, just notate that in your comment and check next time you are here entering and make sure you do follow publicly. There is no further updates from Google on this issue as of right now.
Thank you for your patience!
