FAQ
-
The editor shows the form but the preview only shows a link
-
Save the post again (Update or Publish). WordPress caches oEmbed responses on save. If the first attempt failed, the preview may show only the URL until the cache is refreshed.
-
Do I need to configure anything?
-
No. The plugin only registers the Upcellia oEmbed endpoint. Forms are created and published from the Upcellia admin panel.
-
Does it work without this plugin?
-
WordPress may discover oEmbed via metadata on
f.upcellia.com, but this plugin improves reliability in PHP previews and on the frontend. -
Can I use an iframe instead of oEmbed?
-
Yes. In Upcellia, open Get embed code in the form builder and use the Custom HTML block with the iframe code.
