Dear Kriesi and Dude,
I'm having the same trouble here, the "Sentence Twitter Widget" and "Sentence Twitter and RSS Counts Widget" are not working properly as it should be on my website (andyaron.com).
When I use the "Sentence Twitter Widget", it says "No public tweets found".
In the other hand, I found out that there is only the RSS Count icon displayed while the Twitter Count won't show up using the "Sentence Twitter and RSS Counts Widget."
Can you kindly advise me on how to fix this? Sentence is a good theme, and it's unfortunate if the users, and I, are unable to use its facilities to the max.
Looking forward to your kind and swift reply.
