Hi.
To fix that issue you can change the function: jm_get_filter_resume() on the file:
wp-content/themes/noo-jobmonster/framework/resume/resume-custom-fields.php line 211
with the code below:
if(!function_exists('jm_get_filter_resume')):
function jm_get_filter_resume(){
$resume_filter = jm_get_resume_custom_fields_option('filter_resume');
if (!empty($resume_filter)) {
$resume_filter = !is_array($resume_filter) ? explode(',',$resume_filter) : $resume_filter ;
}
return apply_filters('jm_get_filter_resume',$resume_filter)
}
endif;
Please recheck it.
Regards.
