Hey so I'm pretty new to customizing WHMCS so not sure if what I am asking for is possible or not 😅 I've been using the platform for my business - no problem. However, now I have a client that wants to use me to create their own branding team (they pull in the sales and I do the work) so essentially what they are asking for is to have the webmail login to our shared clients be accessed via their domain (which im hosting ). So I have my clients that log in via my site or their site like normal. What he wants is for his clients that he gets for me, to be able to log onto their webmail via his domain to keep the branding on point. So is it possible to have some of my accounts, have a custom webmail login at a different domain (that im hosting/own)? If not, what would be the best way to achieve this? My second thought is some sort of re-seller account with a fresh whmcs license. Any help would be appreciated and sorry if im making it a bit confusing by the way im writing it🙈

Hello, Wondering if someone can help. I have application links on, but when I go into the Cpanel and click on anything in the billing section I get an oops page. The error message is exception 'Whoops\Exception\ErrorException' with message 'Call to a member function isAllowedToAuthenticate() on null' in /home/bearand1/public_html/WHMCS/vendor/whmcs/whmcs-foundation/lib/ApplicationLink/Server/Server.php:0 Stack trace: #0 /home/bearand1/public_html/WHMCS/vendor/whmcs/whmcs-foundation/lib/Utility/Error/Run.php(0): WHMCS\Utility\Error\Run->handleError(1, 'Call to a membe...', '/home/bearand1/...', 0) #1 [internal function]: WHMCS\Utility\Error\Run->handleShutdown() #2 {main} This only happens on ONE of my clients cpanels. The rest all link accordingly. I tried turning off and then back on the application link to refresh but still same error. Any Help?
