Hi @bruno-martins
I am not sure what you mean by “It does not work” is the Repeater field not saving values? If this is the case, it may be related to the field_name length.
ACF uses the field’s name to save a value into the database. When saving sub fields, the ‘save name’ is generated by the ancestors names + the row index and can become quite long. It is possible that the length of this ‘save name’ can become too long for the wp_options table, and WP will not be able to save the value at all.
You can solve this by reducing the field name length.
If the issue is to do with the field not saving, you can make the following changes to the php.ini file:
max_input_vars = 3000
suhosin.get.max_vars = 3000
suhosin.post.max_vars = 3000
suhosin.request.max_vars = 3000
