Home Page 6 has a search form on it. The "Search" button is not translatable with WPML plugin. WPML support wrote me a message:
Thanks! For a string to be translated, it must be wrapped in a gettext/translatable string (see https://codex.wordpress.org/I18n_for_WordPress_Developers). I did a search at your theme folder and found some strings that are not ready for translation (see screenshot).
There is 2 options in this case:
1) Open the files of the screenshot and replace this:
value="<?php esc_attr_e( 'Search', 'panagea' ); ?>"
This way you should be able to translate the string using the String Translator
IMPORTANT: Please backup your site first before making any change, this is important for security reasons.
2) Contact the support of the theme to fix this at the code of the theme
Please let me know if it worked for you.
I might need your help fixing this.
Thanks and regards,
