Can't integrate SI Captcha (or any captcha) for registration.

Hello,

I’m having problems integrating a captcha for this plugin.

I’ve switched to default themes, deactivated all plugins. SI Captcha seems to work for standard registration at /wp-register.php, however I can’t figure out how to integrate it for the front end forms.

All plugins and WP are up to date.

I’ve tried using your shortcodes as well as echo do_shortcode(). Both have been unsuccessful.

Is there a filter I could include for your plugin or something similar?

I would appreciate any help anyone could provide.

Thank you,
