Using the self-hosted version, v2.0.1, with PHP 8.2 and PHP8.3

I've tested this up to PHP 8.2, and I can't reproduce it. $settings['enhanced_measurements'] is always an array, as it's set in $defaults:

The error thrown says that $settings['enhanced_measurements'] isn't an array, but a string. Which can't happen, as wp_parse_args() makes sure it's an (empty) array.

What I did to try and reproduce it, is the following:

• Delete all settings,
• Set self-hosted domain and domain name,
• Load frontend and wp-admin.

I'm not getting any errors.

Could you provide a more detailed report on how to reproduce it?

Nevermind. I've added this code to make sure it's an array, never hurts to double check 😄
