Problem:
If you're experiencing performance issues after upgrading WPML and the ACFML plugin, where new field group translation code in ACFML is causing many thousand database calls and affecting WP REST API requests, leading to significantly increased response times.
Solution:
We recommend checking the errata page for Advanced Custom Fields Multilingual performance issues at https://wpml.org/errata/advanced-custom-fields-multilingual-performance-issues/.
As a temporary workaround, you can modify the code in

acfml/classes/Strings/STPluginHooks.php

by commenting out the problematic section and setting the plugin status to activated:

public function maybeRegisterFieldGroupsStrings() {<br />    //cbxx ACFML workaround for performance issues<br />    /*<br />    wpml_collect( acf_get_field_groups() )<br />        ->reject( [ $this, 'hasPackage' ] )<br />        ->map( [ $this->translator, 'registerGroupAndFieldsAndLayouts' ] );<br />    */<br /><br />    $this->setPluginStatus( self::PLUGIN_STATUS_ACTIVATED );<br />}

This change should reduce the server load to normal levels. However, please note that this solution might be outdated or not applicable to your case. If the issue persists, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
