Hi John,
Thanks for that, I didn’t even consider the max_input_vars as part of the problem, but in fact it was. Increasing the limit solved the issue and ACF is now able to “update” the current field group JSON file rather than creating a new one.
I didn’t realise my field group is that big now. Probably the only thing that makes me think it was something related to the ACF plugin was that I always got a “field group updated” successful message instead of a warning or error and the fact that it creates another JSON file.
Anyways, thanks for the tip mate.
Cheers,
Milton.
