This plugin appears to be simple, and straightforward, but I'm unsure why I'm getting a 'No tweets found. Please make sure your settings are correct.' message.
I've confirmed all the keys and secrets are correct. I also believe the Twitter username matches the account that retrieved those keys.
One thing I'm thinking is the site is behind a username and password entry. It's a private site. Is this potentially causing problems?
Any thoughts or ideas to look for. I know the account exists and has tweets from as long as 1 hour ago at this time.
