This thread is resolved. Here is a description of the problem and solution.
Problem:
If you're experiencing a JavaScript error in the WordPress admin related to the ACFML (Advanced Custom Fields Multilingual) plugin, where the browser console shows a 'ReferenceError: Can't find variable: wp', this is due to ACFML attempting to call wp.data.dispatch() before the wp object is defined.
Solution:
As a temporary workaround, you can implement a polyfill in your theme's functions.php file. Here's how:
add_action( 'wp_loaded', 'your_custom_fix_acfml_notice', 100 );<br />function your_custom_fix_acfml_notice() {<br /> if ( ! class_exists( '\ACFML\Post\MixedFieldGroupModesHooks' ) ) {<br /> return;<br /> }<br /> add_action( 'wp_print_scripts', 'your_acfml_polyfill', 1 );<br />}<br />function your_acfml_polyfill() {<br /> ?><br /> if ( typeof wp === 'undefined' ) {<br /> window.wp = {};<br /> }<br /> if ( typeof wp.data === 'undefined' ) {<br /> window.wp.data = {<br /> dispatch: function(store) {<br /> return {<br /> createNotice: function(type, message, options) {<br /> document.addEventListener('DOMContentLoaded', function() {<br /> if (window.wp && window.wp.data && window.wp.data.dispatch) {<br /> window.wp.data.dispatch(store).createNotice(type, message, options);<br /> }<br /> });<br /> }<br /> };<br /> }<br /> };<br /> }<br /> <?php<br />}<br />This workaround prevents the error until the real wp.data becomes available. However, this is only a temporary solution. We have escalated this issue to our development team, and it should be addressed in the upcoming ACFML release 3.0.0.
