Ok, so you want to merge your bands Reverbnation profile with your wordpress website and you have installed the official WP plugin (v0.1 at the time) but it’s not working when you put the shortcode into a text widget? There are two possible reasons for this:
1. Your WP theme does not support executing shortcode from widgets – find a fix here.
2. ReverbNation server sources are commented out in reverbnation-widgets.php – find this file via FTP or through Dashboard and comment out ‘Development’ sources and enable the ‘Production’ ones. It should look like this:
That should do it.
One more thing – you should probably use HTML source-code ReverbNation provides if you have an account there instead of this plugin because it’s much more versatile and provides you with more options to manipulate the appearance of ReverbNation widgets looks (v0.1).
