Twitter sidebox Cached

[paulm]

There are no php error logs related to the twitter sidebox. However, I did take a look at twitter_cache.xml. When the sidebox displays nothing, this is what the XML file looks like:

<hash><error>Rate limit exceeded. Clients may not make more than 150 requests per hour.</error><request>/statuses/user_timeline/fredssupply.xml?count=25</request></hash>

Why am I exceeding the rate limit? I thought that was the whole point of having the cache.... please advise and thank you for your help.

Are you using the version from this thread? (1.10) Of the one from the downloads section? (1.03)
