Our PHP settings of max_input_vars = 5000, we are not using JSON. About field_name, we tried to change field name but still no changes.
My option_name in DB looks like that:
option_name varchar(191) utf8mb4_unicode_ci Yes NULL
We tried to add Page Link field outside the repeater, and this is working. So seems like the problems is only inside repeater fields. But it was working this way for few years, why would suddenly stopped working? Any other clue?
