I would like to translate using the Translation Management from WPML, cause that’s a more professional. Just copying the whole site and editing takes a lot of time when having multiple languages. we have 4.
Like in this post:

https://wpml.org/forums/topic/unable-to-translate-fields-using-visual-composer-and-fortuna-theme-shortcodes/

Can you please help me creating the wpml-config.xml?

thanks

Lets see, you want to translate labels like the names of the shortcodes?
You should be able to do that by simply generating a PO & MO files for your language then plug it in the languages folder, then switch the language in the admin.
Or you want to translate actual page content like you posted on WPML forum? What am I missing?

<wpml-config>
    <custom-types>
        <custom-type translate="1">portfolio</custom-type>
    </custom-types>
    <taxonomies>
        <taxonomy translate="1">portfolio_category</taxonomy>
    </taxonomies>
    <admin-texts>
        <key name="option_tree">
            <key name="logo_upload"/>
            <key name="logo_upload_retina"/>
            <key name="favicon_uploaded"/>
            <key name="copyrights"/>
            <key name="woo_static_top_content"/></key>
    </admin-texts>
    <shortcodes>
        <shortcode>
            <tag>boc_heading</tag>
        </shortcode>
        <shortcode>

                <attribute>title</attribute>
                <attribute>btn_content</attribute>
                <attribute>href</attribute>
            </attributes>
        </shortcode>
        <shortcode>
            <tag>boc_button</tag>
            <attributes>
                <attribute>btn_content</attribute>
                <attribute>href</attribute>
            </attributes>
        </shortcode>
        <shortcode>
            <tag>boc_list_item</tag>
        </shortcode>
        <shortcode>
            <tag>vc_column_text</tag>
        </shortcode>
        <shortcode>
            <tag>vc_text_separator</tag>
            <attributes>
                <attribute>title</attribute>
            </attributes>
        </shortcode>
    </shortcodes>
</wpml-config>

these are the shortcodes/elements my customers used. feel free to implement it to your theme when it’s complete

best wishes,
Felix
