If WPML is configured to sync the page order between translations, it is impossible to change the menu_order
of a fieldgroup. The value always stays the same.
As soon as page ordering sync in WPML is disabled, changing menu_order
works fine again.
WP 3.8.3, ACF PRO 5.0.0, WPML 3.1.6
Hi @thomask
Thanks for the bug report. This is a strange one because you would think that WPML uses the most recent post’s menu_order and syncs it with the others…
I’ll do some testing with this too
