The plugin is exactly what we needed, thanks! After installing we came upon the following problem though: the Twitter user avatars wouldn't load. This is due to an SSL certificate error with the servers a0.twimg.com, a3.twimg.com and so forth. The feed page on the blog also displays certificate error messages, which is confusing and alarming for users. This happens when viewing the blog over https.
This is due to the plugin trying to use the abovementioned servers instead of twimg0-a.akamaihd.net, twimg3-a.akamaihd.net and so forth that Twitter itself uses. The file names and paths seem to be absolutely the same regardless of the server, and the server number can be anything from 0 to 6.
