Please provide a link where I can get latest version of WHMCS
Current WHMCS version is: 7.7.1. You can download it here: https://my.westnic.net/whmcs/whmcs_v771_full.zip. If you're installing new WHMCS, you should use "Softaculous" within cPanel. Please note: WestNIC and Softaculous don't monitor versions of WHMCS. WHMCS releases more and more updates and patches every single month. Please check official website: whmcs.com for latest updates and changes.
