This thread is resolved. Here is a description of the problem and solution.
Problem:
After updating WPML and other plugins, a critical error occurs on some WooCommerce product pages when the WPML String Translation plugin is active. Deactivating the plugin resolves the issue temporarily.
Solution:
To permanently fix the issue, modify the code in two files:
1. Navigate to
/wp-content/plugins/sitepress-multilingual-cms/addons/wpml-page-builders/classes/Integrations/Elementor/DataConvert.php
and replace the unserializeString function with the following code:
private static function unserializeString( $string, $associative ) {<br /> // phpcs:ignore WordPress.PHP.DiscouragedPHPFunctions.serialize_unserialize<br /> $value = is_serialized( $string ) ? unserialize( $string ) : json_decode( $string, $associative );<br /> if ($value === null){<br /> return $string;<br /> }<br /> return $value;<br />}2. Go to
/wp-content/plugins/sitepress-multilingual-cms/addons/wpml-page-builders/classes/Integrations/Elementor/Hooks/QueryFilter.php
and replace the translateQueryIds function with:
public function translateQueryIds( $value, $object_id, $meta_key, $single ) {<br /> if ( WPML_Elementor_Data_Settings::META_KEY_DATA === $meta_key && $single ) {<br /> $value = get_post_meta( $object_id, WPML_Elementor_Data_Settings::META_KEY_DATA, true );<br /> if ( $value ) {<br /> $value = DataConvert::unserialize( $value, false );<br /> $value = this->recursivelyTranslateQueryIds( $value );<br /> if (is_array($value)) {<br /> $value = DataConvert::serialize($value, false);<br /> }<br /> }<br /> }<br /><br /> return $value;<br />}After making these changes, save the files. This solution was successfully applied to a staging site, resolving the issue.
