For your first issue, please contact with WHMCS Bridge Support to get help. In this issue, we are unable to help.
2nd, mainly WHMCS Bridge Plugin connect WHMCS in an iframe without header & footer of WHMCS template. That’s why, when you are visiting https://www.aklwebhost.com/clientarea/ it shows WHMCS template within WHMCS Bridge Plugin’s iframe with your website header & footer.
However, if you want to use/access the WHMCS template separately like http://www.aklwebhost.com/client then you must have to customize the WHMCS template, specially the header, footer & color of WHMCS template based on your website header, footer & color. Also, need to update the menu links based on your website.
Hope you understand.
Best Regards,
