Problem:
If you're experiencing issues with the

get_terms

function returning an empty array for translated terms in a multilingual setup using WPML, consider following.

Solution:
Firstly, ensure you're using the correct syntax for the

get_terms

function. Since WordPress 4.5.0, taxonomies should be passed via the 'taxonomy' argument in the

$args

array. Here's an example of how to use it correctly:

$terms = get_terms( array(
    'taxonomy' => 'post_tag',
    'hide_empty' => false,
) );

Next, consider reviewing the following resources for additional guidance:

• WPML forum discussion on getting translated terms
• WPML forum discussion on correlating translated and base language terms

Also, take a look at the WPML Hooks Reference for additional hooks and examples that might be helpful, especially the

wpml_get_element_translations

hook.

If these suggestions do not resolve your issue, and you're not comfortable with custom coding, you might want to consider hiring a developer. You can find qualified contractors at https://wpml.org/contractors/.
