[Resolved] ACF translations and in some cases translation doesnt save

Problem:
You are unable to save translations on your homepage and Advanced Custom Fields using WPML after reaching 100% and clicking 'Complete'. The translation does not save, and the '+' icon reappears.
Solution:
We recommend following these steps to resolve the issue:
1. Create a full backup of your site.
2. Update all outdated plugins, themes, and the WordPress core. Update the WPML plugins by navigating to Plugins -> Add new -> Commercial tab -> Click on the button to get new updates.
3. Flush any cache memory that might exist.
4. Insert the following code into the functions.php file within your theme's folder:

function wpmlsupp_1891_fix_missing_icl_tables() {
    if( function_exists( 'icl_sitepress_activate' ) )
        icl_sitepress_activate();
}
add_action( 'wp_footer', 'wpmlsupp_1891_fix_missing_icl_tables' );

5. Visit the page in the frontend.
6. Remove the code from the functions.php file.
7. Check if the issue is resolved.

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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. If the problem persists, please open a new support ticket at WPML support forum.
