Problem:
I would like to place a custom language switcher in the top right corner of the header (I have 1 global header and 2 custom headers made with Divi Theme Builder)

Solution:
Place the custom language switcher shortcode [wpml_language_selector_widget] in the Divi code module in the global header made with Divi builder.

That shortcode outputs the language switcher based on the options set in the Custom Language Switchers section.

Problem:
The advanced custom field relationship is not translated, the English field has Arabic values, not the English ones. Relationship fields are set to Translate.

Solution:
- Go to ACF > Fields groups > Edit and set your relationships field to Copy, so the same value is copied to the translated post.

- Go to default language post and click Update so correct values are now synced and copied.

Problem:

Is there an option to migrate from the WP Multilang plugin to WPML?

Solution:

I'm sorry but this multilingual plugin is not known to us and we don't have a special option or procedure for migrating content from a WordPress site that used this plugin. We do have some recommended procedures to migrate content from other multilingual plugins like qTranslate and Polylang.

You can also try to use the importer feature which is built-in in WordPress.

When you import the content and WPML is active you can choose the language of the imported content. Please see the attached screenshot.

And you can also use the WP All Import plugin which officially compatible with WPML.

Problem:
I have set up a bunch of custom fields for a post type using ACF. These will be translated using the translation editor. However, the custom fields appear in the order that they were added to the database, which does not match the order they are in when editing the posts. The order of custom fields in the posts follows that of the ACF field group and this order can be re-arranged, for example after adding more custom fields.

Solution:
WPML is not made to update based on the order changes that you made on the field group. This is gonna work only on the WordPress editor, but the WPML translation editor has no logic implemented for this.

Problem:
I am trying to translate a page from English to Chinese. I expected to see the masonry gallery exactly the same both on the original and translated page.

Solution:
Edit each image of the Masonry Gallery through Dashboard → Media library (in list view). Open one of the images, and check the value of the Masonry Image Layout option at the bottom of the page. Now, change the language using the top admin language selector and make sure that this custom field has the same value. Once you did this, just simply update the image and that's all.

Just make sure that you did this for all the images of the masonry gallery.

Problem:
I can't login to /wp-admin following fatal error: Uncaught Error: Call to undefined function simplexml_load_file()

Solution:
The SimpleXML extension is not active on the server. Forcing a re-install of XML solved it.

apt-get --reinstall install php7.3-xml

Check the errata link.

Problem:

The currency parameter for WooCommerce Google Product Feed and Currency is not working.

Solution:

Add the following function to the functions.php file of the theme.

add_filter( 'wcml_client_currency', 'modify_client_currency', 10, 1 );
   
function modify_client_currency( $current_currency ) {
    if( !is_admin() ){
        global $woocommerce;
   
        $currency = isset( $_GET['currency'] ) ? esc_attr( $_GET['currency'] ) : $current_currency;
        $currency = strtoupper( $currency );
   
        $woocommerce->session->set('client_currency', $currency);
   
        return $currency;
      }
}

This is a suggestion that worked in this specific case. We can not guarantee that it would work in any case.
