From what I see in the code, this plugin just changes the folder in which the JSON files from ACF are saved, from the theme folder to the uploads folder.

In my opinion, this just makes sense if you have permissions problem when writing to the themes folder.

I work a lot with ACF and always looking arund for better, smarter performance. Please explain what the method this plugin uses to change the built in json file cache. We like contributors!

I’ve installed the plugin. But there are no generated JSON files in the acf-json folder after updating a field group. I’ve set the folder permissions to writable. But how do cache the plugin the field groups? Do the main feature of the ACF plugin do the same as your plugin? Generating JSON-Files?
