Hello,
Thanks for the feedback!
In fact, I was able to reproduce the bug. The issue come from the latest ACF 6.3.10 version which added some additional nonce check for fields ajax requests.
The latest ACF Extended 0.9.0.8 patch added compatibility fixes regarding this, but the ACFE Taxonomy Terms field wasn’t fixed. It is an oversight. I’m adding a fix in the next patch.
In the meantime, you can fix the issue by adding the following code in your theme’s functions.php
file:
// ACFE 0.9.0.8: Fix taxonomy terms ajax nonce wih ACF 6.3.10
add_filter('acf/prepare_field/type=acfe_taxonomy_terms', 'acfe_fix_taxonomy_terms_ajax_nonce');
function acfe_fix_taxonomy_terms_ajax_nonce($field){
if($field['ui'] && $field['ajax']){
$field['nonce'] = wp_create_nonce($field['key']);
}
return $field;
}
Thanks again for the report, and sorry for the inconvenience.
Regards.
