Need help in few changes

[meudayg1]

Hi All,

 

I'm new to this forum and very less exposed to coding stuff. Please help me on below issue.

 

We are using below code for license validations and due to some technical challenges our server is going down which in turn effecting our users I want to make few changes like

 

• Even if our server is down for some time it should not impact our users(their site should not be down) or
  
• Temporarily disable license validations or
  
• user site should not check for license (week or month).
  

 

 

function check_license($licensekey, $localkey = '') {
$whmcsurl = 'http://abc.com/license';
$licensing_secret_key = 'xyzabd123*******';
$check_token = time(  ) . md5( mt_rand( 1000000000, 9999999999 ) . $licensekey );
date( 'Ymd' );
$checkdate = ;
$usersip = (isset( $_SERVER['SERVER_ADDR'] ) ? $_SERVER['SERVER_ADDR'] : $_SERVER['LOCAL_ADDR']);
