Hi there,
This issue has been reported about 40 days ago, and still no answer from the support – which is pretty strange, especially because this is a serious issue.
Folks experiencing the same issue: downgrade to version 6.2.6.1, this process fixed the issue for me.
(And based on the silence in this topic room, and on the WP-WPEngine legal war, I wouldn’t count on a fix being published soon…)
Definitely not a possible workaround on a client production site. ¯\_(ツ)_/¯
I find it pretty strange (and let’s be honest, pretty frustrating) that a plugin of this magnitude and complexity doesn’t include such basic functionality.
The above snippet doesn’t work anymore, not in 2023 at least.
The fix seems to be simply removing the second function and its hooking.
(When this second function is active, it breaks things in the backend – notably, all field groups not having a post type display rule get displayed on post list and post edit screens. Ugly!!)
I’m having this issue since the first beta of v5.
I just updated to version 5.7.2 and still have the issue.
The strange thing is that not everybody working on the site(s) experiences it.
The otehr strange thing is that the page updates can be saved by clicking in the title field and hitting enter. It’s specifically the Publish button that doesn’t work => AJAX stuff.
Finally – this issue not only affects pages, but menus as well. It’s totally impossible to save any menu change if ACF 5 is active.
