Error – Division by zero on Embed

[OC2PS]

News Pro is returning the error
Warning: Division by zero in public_html/wp-includes/theme-compat/embed-content.php on line 33
when I embed a link from the same WordPress site in a post.

See: https://hennalap.com/hajfestes-henna/

Metro Pro, running on a different site but same server, seems not to have the issue:

Arjhay, az elkötelezett arcfest?‘ – interjú

This is weird... I thought WordPress falls back on Theme Compat only if a theme does not have the needed template, and that Genesis child themes are merely a bunch of CSS to modify the look of Genesis. Metro Pro working would indicate that Genesis has embed-content.php template, and yet News Pro is falling back on Theme Compat.

P.S. In the above post, why did arcfestesmintak.hu site URL's anchor text become the post title, while for the hennalap.com site, the URL became the anchor text?

Genesis does not have an embed-content.php template. Neither News Pro nor Genesis is responsible for generating your error. You'll have to turn on WordPress debug to dive deeper into the problem.

I understand that the error is coming from the embed-content template in Theme Compat. Question is: How come the site using News Pro has to fallback on Theme Compat at all when the one using Metro Pro doesn't?

How do you know Metro Pro isn't using embed-content.php? Did you run a trace or are you making an assumption because there is no error?

If you look at the source code of embed-content.php at line 33, you'll see:

if ( $data['width'] / $data['height'] > $aspect_ratio ) {

The $data array referred to in this line comes from:

wp_get_attachment_metadata( $thumbnail_id )

This means the content you are trying to embed is missing its height dimension. The height dimension is missing or set to 0, that's why you get a divide by zero error. This is all WordPress code. It has nothing to do with Genesis or the News Pro theme. You are passing bad data to the embed.

You are right - the error has nothing to do with the child theme - in the problematic site, I changed theme to Metro Pro, and still got the error.

Finding it hard to diagnose the issue - both sites have almost identical list of installed plugins and both are on the same server.

I tried turning wp_debug on, and above the embedded links, I got the error:
Strict Standards: call_user_func_array() expects parameter 1 to be a valid callback, non-static method Genesis_Tabs::init() should not be called statically in /public_html/wp-includes/class-wp-hook.php on line 298

Genesis Tabs - which is an integral part of the News Pro child theme look and feel, is installed only on the site that currently has the issue.
