I’m not the plugin author – I was just suggesting a temporary fix until the plugin was fixed. Looks like the 1.6.3 version fixes this problem.
And that problem was not fixed with 1.6.2 – I just installed it and the plugin has the same problem.
Go into the WordPress plugins editor and select this plugin.
There will be one or two characters showing before the <?php in the plugin code – delete these characters and save the plugin code and the problem should be resolved… at least this resolved all of the ‘headers already generated’ problems…
There are characters in the main plugin php file ahead of the <?php that is not a BOM and causes a header to start being generated inappropriately.
