Limit of 1000 fields in POST method
One setting away from fixing the problem

max_input_vars = 5000
You need to change this value in your php.ini. It may be either php.ini of your Apache, eg.:/etc/php5/apache2/php.ini:
Or php.ini placed inside root directory of a website, eg.:/home/my_username/public_html/php.ini
or .user.ini:/home/my_username/public_html/.user.ini
Or even inside .htaccess file.
