Product admin page breaking with too many product variations [closed]

I had the same issue in a client site which turned out to be a php POST variable limit (1000) which is an attempt for PHP to solve some security issues. This can be easily changed via the php.ini config file ex:
max_input_vars = 5000

you should also note the max_input_nesting_level

But we ended up using a grouped products instead of variations.
