I've added some options to php.ini but nothing seems to help. I used phpinfo() to make sure the changes went live and they did.
Values i tried to change:
max_input_vars = 50000 (tried also 3000, 5000 and 10000, default was 1000)
max_input_nesting_level = 256 (default was 64)
post_max_size = 128M (default was 8M)
Can you give me any other clues?
