Hey folks,
If you’re getting this error, and you’ve upgraded to ACF 6.4.0, it means you’ve code in your custom plugins or theme that is forcing ACF to initialise too early.
This is likely to be called like get_field or acf_add_options_page.
Once you’ve found the ACF calls which are happening too early, you can wrap the code in:
add_action('acf/init', function() { [existing code] });
to resolve this error.
Thanks,
Liam
