Hi All,

Getting this message in the control panel dashboard and don't know which file and where it is to fix.

WARNING: Your PHP max_input_vars setting is set to a low value. Your current setting is 1000; the default setting is 1000. Based on your current number of forums, a minimum setting of 4350 is recommended. Your forum may have issues such as a blank configuration file, missing settings, or unexpected script behavior if you continue. Please see the "Issues with the PHP 'max_input_vars' Setting" entry on the UBBWiki for more information.

Any detailed information on where the file is and what to do would be a great help.
