Property Fields loses some settings when saved

The cause of this problem is the small value of the “max_input_vars” option in the configuration of your server (host). You should increase the value of the “max_input_vars“. You need to set a larger value. You can try to increase it in one of the ways that are described below.

• Most hosts have the opportunity to change this value in the “Host Admin Area”.
  Example:
  If currently you have max_input_vars = 1000
  You need to set max_input_vars = 9000
• You can try to change this value using the “.htaccess” file in the root directory of your site. Add the following lines of the code at the end of “.htaccess” file:

  php_value max_input_vars 9000
  php_value suhosin.post.max_vars 9000
  php_value suhosin.request.max_vars 9000

• You can try to change this value using “php.ini”. Try to find “max_input_vars” and change the value for this variable. If the line of the code in your “php.ini” look like this:

  ; max_input_vars = 1000

  Then change it to the following:

  max_input_vars = 9000

• If that does not help you, ask your host support “How can I increase the value of the max_input_vars for my site?”
