I thought mo:blog don't work with the new blogger thingy because of the incredibly long new user id. So I created a new one, but it didn't work either.
Then I thought new blogger no longer support this thing call API. No, it's not the Malay word for 'fire'. It's a computer programming term.
I searched for the fix. Even downloaded and re-install the mo:blog in my T5. Still it wouldn't work.
Just now I chanced upon a website for developers (can't remember the URL). Glancing through a bunch of programming codes, I saw the word 'uri'. Similar word is in the mo:blog settings. So I tried replacing the 'www' in the settings, with 'beta'. It worked!
