Problem with function now in class

Hi

Great job putting the code into a class – the right thing to do. 🙂

However my site was using the PHP call to the function, like this:
echo pplb_logout_button();

After updating your plugin I got PHP errors that the function was not found, so I had to change my code to this:
$pplb = new PPLB_Plugin(); echo $pplb->pplb_logout_button();

You might want to update your advice on the settings page and/or provide a backup function so that users like me don’t get struck with PHP fatal errors.

Thanks for the plugin though – nice work 🙂
