Each time you update your WHMCS, incremental or full update, check if the clientareadomaindetails.tpl file has been overwritten. In such case you need to add again the required modifications:
Template file clientareadomaindetails.tpl
If no changes have been made by whmcs, re-upload the clientareadomaindetails.tpl file from your previous version. Otherwise, you need to add the necessary modifications as per the installation documentation for RAMDI, REMDI and RAMEI:
