I've been having these problems from the morning - 401 errors authentication required. I managed to do a bit of editing and writing every now and then - it wasn't a problem as long as it used to be back in 5 mins. But, now I'm here but can't edit pages as whenever I click edit, I'm taken to the login window (The popup). I log in and then its back to the home page and the cycle repeats.
Any suggestions? I'm going to give up for now will continue tomorrow. But looking for help if possible
