WordPress 6.7 Debug Message: “code in the plugin or theme running too early”

Hello there! We’ve recently started experiencing the following error log message when running our websites in debug mode. Our sites are running WordPress 6.7.1 on PHP 8.2.

PHP Notice:  Function _load_textdomain_just_in_time was called <strong>incorrectly</strong>. Translation loading for the <code>acf-icomoon</code> domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the <code>init</code> action or later. Please see <a href="https://developer.ww.wp.xz.cn/advanced-administration/debug/debug-wordpress/">Debugging in WordPress</a> for more information. (This message was added in version 6.7.0.) in /home/webuser/public_html/wp-includes/functions.php on line 6114

We’ve traced the source of this message to the main acf-icomoon.php file in the plugin’s root folder. We have been patching this locally on sites we manage with the following change…

Perhaps you’ll have another way you’d want to address this error message, but at the very least we wanted to bring it to your attention. 🙂
