Dear Nick,
As you mentioned in one of your replies that you have worked for WHMCS. Also, offered us your service. We thought you are more experienced than us to solve these types of small issues.
Moreover, we didn’t find anything on your provided link.
Also, let us know your WordPress version and your hosting server PHP verion to understand the issue.
OR, please provide your cPanel and wp-admin (URL, Username & Password) access using our Envato Market (codecanyon) profile contact form https://codecanyon.net/user/themelooks#contact (screenshot as reference https://prnt.sc/10o0iwt ) including this support topic link as a reference to review the issue to assist.
Best Regards,
ThemeLooks Support Team
