Hi @lapzor.
When I made a test page, the shortcode did not show up.
Then it dawned on me that it didn’t show up because the shortcode I used was a modal one, not an inline one.
ConvertKit allows you to make various types of optins, including inline and modal. My thinking was that since Boxzilla was a pop-up, the modal would be appropriate. Then I realized that I was in a way “outsourcing” that modal function from Convertkit to Boxzilla, so I needed to pick the type of optin form that allowed it to just show up. That’s what the inline form does.
So I switched the form from a modal form to an inline form in ConvertKit, tested the shortcode again, and it showed up on the test page. Then I put the new code in the plugin, deleted my cache, and it showed up without a problem.
Thanks! ??
