Problem:
The client reported an issue where the WPML menu synchronization process gets stuck at 'Syncing menus 0 of 35'. Despite bypassing Cloudflare, which usually causes timeouts, the process hangs indefinitely without any errors in the console or network. The client considered modifying the synchronization code to handle batches by skipping certain languages.

Solution:
We recommended modifying the

get_menus_tree

function in the

sitepress-multilingual-cms/inc/wp-nav-menus/menus-sync.php

file. The suggested code adjustment involves using transients to store menu data temporarily, which helps in managing the load during synchronization. Here is the code snippet provided:

function get_menus_tree() {
    global $sitepress, $wpdb;

    $menus = $wpdb->get_results(
        $wpdb->prepare(
            "
            SELECT tm.term_id, tm.name FROM {$wpdb->terms} tm 
                JOIN {$wpdb->term_taxonomy} tx ON tx.term_id = tm.term_id
                JOIN {$wpdb->prefix}icl_translations tr ON tr.element_id = tx.term_taxonomy_id AND tr.element_type='tax_nav_menu'
            WHERE tr.language_code=%s
        ",
            $sitepress->get_default_language()
        )
    );

    if ( $menus ) {
        foreach ( $menus as $menu ) {
            $menuproc = get_transient("menu_term_id". $menu->term_id );
            if (empty($menuproc)) {
                $this->menus[$menu->term_id] = array(
                    'name' => $menu->name,
                    'items' => $this->get_menu_items($menu->term_id, true),
                    'translations' => $this->get_menu_translations($menu->term_id),
                );
                set_transient("menu_term_id". $menu->term_id, $this->menus[$menu->term_id] );
            } else {
                $this->menus[$menu->term_id] = $menuproc;
            }
        }

        $this->add_ghost_entries();
        $this->set_new_menu_order();
    }
}

We advised the client to implement this change on a staging site first to ensure everything functions correctly without disrupting the live site.

If this solution does not resolve your issue, or if it seems outdated or irrelevant to your specific case, please visit our known issues page and check for any updates. We also recommend ensuring that you have the latest versions of themes and plugins installed. If the problem persists, do not hesitate to open a new support ticket.

Problem:
After upgrading to WPML Multilingual CMS v. 4.9.0, WPML String Translation v.3.5.0, and WPML Media Translation v.3.1.0, clicking 'Save and Complete' in WPML causes the icons to keep rotating, and an error appears in the developer console indicating a 'SyntaxError: Failed to execute 'json' on 'Response': Unexpected end of JSON input'. This issue persists even after refreshing the page and clearing the cache.
Solution:
We have identified that this issue typically occurs when the WordPress REST API is disabled, which WPML and its Advanced Translation Editor rely on for fetching data. If you're experiencing this issue, we recommend checking if any plugin, theme function, or server setting might have disabled the REST API. Specifically, if you have a plugin named 'Disable REST API' activated, please disable it and test again.

If this solution does not resolve the issue or seems irrelevant due to being outdated or not applicable to your case, 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.
