As of today, whenever I go to log in to my wikidot account while using Firefox, it rejects the login and gives me a blank page that says only 'No valid session found.' Yesterday, I had no difficulty logging in. I haven't added anything to Firefox, or made any other changes; the only abnormal thing I've done in the last 24 hours is run an antivirus scan overnight. I tried clearing cookies, clearing private data, and reinstalling Firefox, none of which have had any effect.
I have no difficulty logging in while using Internet Explorer.
Does anyone have any ideas on what is causing this and how I can fix it?
