Analytics Episode Details: Graphs not showing up

[kl1lercher]

Expected behavior

Episode Details in Analytics used to show bars and filtering was available by clicking on different properties

Actual behavior

Analytics Episode Details not showing up after i've updated to 4.x. Analytics Overview, the startpage, is showing data.
To be fair, i recently reactivated analytics after it was disabled for years.

Thanks for the report! Fixed in next release.

Hate to do this, but graphs are unfortunately still not showing up.
Console just showing a Server Error 500 for i guess the necessary component

@kl1lercher can you check your PHP error log? The 500 response means the PHP script fails for some reason.

You may need to enable debug logging first, see https://wordpress.org/documentation/article/debugging-in-wordpress/

Well dividing by zero is tough 😬

PHP Fatal error: Uncaught DivisionByZeroError: Division by zero in [...]/podlove-podcasting-plugin-for-wordpress/lib/ajax/ajax.php:229

Should be an easy fix, thanks for looking up the error!
