The amount of data that the page is submitting exceeds the limit in the following PHP configuration variables:

• max_input_vars
• post_max_size

To increase the amount of data that you can submit, edit the php.ini configuration file on your server to increase the max_input_vars and post_max_size  variables.

Your server configuration may allow you to change the PHP configuration for WHMCS by creating a php.ini file within the WHMCS directory and adding the following line:

max_input_vars='9000' 
post_max_size= '10M'

The example above will allow the system to save up to 9000 pieces of data.
