I have been use ACF Pro from when I started work with WordPress. I think that this is great tool to fast make websites.

Very oft I use Flexible Content to build pages – customers and content managers are happy with make pages with this module.

In last time I saw problems with create fields for Flexible Content.

I use this method to save fields details: https://www.advancedcustomfields.com/resources/local-json/

In tab “Sync availble” I see my group: “Flexible Content – group_5a3d44418d526.json”. Then I click “sync” link. My group have 4 fields – one of is flexible content.

I have defined 23 layouts with 243 fields. File group_5a3d44418d526.json have 234KB and 5230 lines.

When I try add new field to layout and save this change then I see that in my directory created is new file: group_5a3edb613ffa2.json, and previous file was not modifed.

When I compare two files then I see differences. Some fields was removed, some fields was move to another layout, settings of visibility field group was changed (remove location, hide on screen), and new field not exists.

I use PHP 7.1.12, ACF Pro 5.6.7 and WordPress 4.9.1

This is importat bug in my opinion. If I did’nt use local json and GIT, I probably would not know about the problem.

There is a plugin that will alert you to problems with max_input_vars https://wordpress.org/plugins/wp-max-submit-protect/

I use this plugin on all sites that I’m developing.
