PHP Fatal error: Uncaught Error: Call to undefined function wp_generate_attachm

Hi,

WP Version 6.5.5 and PHP 8.2 (tried also 8.1).

The error:

[13-Oct-2025 09:09:52 UTC] PHP Fatal error:  Uncaught Error: Call to undefined function wp_generate_attachment_metadata() in /home/public_html/wp-content/plugins/directorist/includes/classes/class-background-image-process.php:83

Any ideas?

I wun Directorist Version 7.12.7 because updating to 8x doesn’t work well for me and i can’t solve the issue.

Thanks
