shortcode does not display anything anymore

This is to verify that we have updated a test environment to WordPress 6.0.2 and the plugin no longer works for us either.

We will look into fixing it, but we don’t do a lot of active WordPress development so we welcome any suggestions people have about what might be the root issue.

In WordPress 6 you can use a “Custom HTML” block and drop in the iframe embed code from the Timeline site.

Of course, we understand that existing WordPress installs would prefer that their pages not “break”, and we’ll see if we can fix it… but

Also, the oembed feature enabled by the plugin still works, so you can include the URL to a timeline (such as https://cdn.knightlab.com/libs/timeline3/latest/embed/index.html?source=1xuY4upIooEeszZ_lCmeNx24eSFWe0rHe9ZdqH2xqVNk&font=Default&lang=en&initial_zoom=2&height=100% ) on a line by itself and it should work, although there’s less control over the dimensions of the embedded timeline.
