Hi Guys,
I appear to have fixed this issue for myself (on WordPress 3.8), the problem seemed to lie in the returned transient data via wordpress not supplying valid JSON.
To remedy this I simply base64_encode() my $tweets before I set_transient(), and base64_decode() before I json_decode().
I have posted my modified inc/get_tweets.php (from v1.4.4) to PasteBin:

Good luck!

From what i can tell, the approval system is in reverse, EG untick the setting boxes = Approval on and tick = off.
As i had the same problem, and this just worked for me 🙂
