I just installed the plugin on two separate sites (also separate hosts, and separate twitter accounts), and noticed that:
on one site I get a 150 limit
on the other a 20000 limit
Both sites however, use more API calls than 1 per 5 minutes.
With the result that the 150 limit one, finishes this limit in under half an hour. In fact, just now the limit should have been reset, but 8 minutes into it, with a non-busy website, 150 have been used again.
Or maybe still? Is it possible something else is wrong so that it just keeps hanging at 150 used?
The main problem though, is that no tweets appear on the page in this situation. I don't see any cached tweets.
Is there anything to be done that makes sure the latest set of tweets remains on the site until the limit is reset? Currently, I get white space once the 150 are gone.
