If you are experiencing issues during saving large amounts of data - it may mean that your server is not properly configured and does not allow you to save large amounts of data. Data entered in the configuration of the plugins can be cut off and not saved in the database.

There is a max_input_vars PHP parameter that controls how much data can be saved at one time. The default value is 1000 which can be too low for some scenarios.

Solving the problem may look different on different web servers, but in most cases, you need to add this line to your .htaccess file:

php_value max_input_vars 2000

If this does not solve the problem in your case, please consider changing it to a higher value (3000). If it still does not help, please contact your hosting provider and ask for support.
