Why am I getting a Share This page instead of popup?

Firstly, make sure that the <?php wp_footer(); ?> call is included in your template, usually in footer.php. Without this, the popup wont work. This will fix 99% of issues.

If you're still not getting the popup, make sure you've turned on the relevant setting in the options page, and try saving and / or resetting the options.
