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.

Hello, We are encountering a JavaScript error in the WordPress admin that appears to be caused by the ACFML (Advanced Custom Fields Multilingual) plugin. On the page edit screen in the admin, the browser console shows the following error: ReferenceError: Can't find variable: wp From what we can see, ACFML attempts to call wp.data.dispatch() to display a notice, but the global wp object is not yet defined at that moment. This leads to the console error. Temporary workaround As a temporary workaround, we implemented a small polyfill in our theme (functions.php) that prevents the error by defining a minimal wp.data.dispatch() until the real wp.data becomes available. Example of the workaround: add_action( 'wp_loaded', 'vogelwarte_fix_acfml_notice', 100 ); function vogelwarte_fix_acfml_notice() { add_action( 'wp_print_scripts', 'vogelwarte_acfml_polyfill', 1 ); function vogelwarte_acfml_polyfill() { if ( typeof wp === 'undefined' ) { if ( typeof wp.data === 'undefined' ) { <?php This removes the console error, but it is clearly only a workaround and ideally should be handled inside the plugin. Could you please investigate why ACFML triggers wp.data.dispatch() before the wp object is available and provide a proper fix? Environment: WPML plugins: ACF plugin: Thank you!  |

Hello, Thank you for the update and for sharing the details. I checked the page from my side and at the moment I’m not seeing the same. I also switched the editor to the WordPress editor, which is the correct approach when editing translated content manually and saving it. Could you please check again on your side and confirm if the error is still appearing? If possible, please share if I need to do anything else other then Save FR draft and enable logs and show all message / errors in browser console. Kind regards,  |
