PHP Warning – Undefined array key “term_rel”

Hi Team,

I noticed a few of our sites are showing the following error:

Warning: Undefined array key “term_rel” in /home/customer/www/domain-name.com/public_html/wp-content/themes/enfold/config-templatebuilder/avia-shortcodes/blog/blog.php on line 562

It seems to be when a short code is used to display blog posts or shop categories on a page.

Is this fixed in the upcoming ENFOLD version 5.6.5.?

For now, I’ve hidden the PHP error on the front end of WordPress by adding the following to the wp-config file, just before the /* That’s all, stop editing! Happy publishing. */ line:

ini_set('display_errors','Off');
ini_set('error_reporting', E_ALL );
define('WP_DEBUG', false);
define('WP_DEBUG_DISPLAY', false);

The affected sites are running PHP 8.2.8 with ENFOLD 5.6.4 and WordPress 6.2.2.

The error remains even with all plugins disabled.
