Whoops\Exception\ErrorException: Module 'soap' already loaded in Unknown:0
Stack trace:
#0 /var/www/xxx.co.uk/public_html/vendor/whmcs/whmcs-foundation/lib/Utility/Error/Run.php(0): WHMCS\Utility\Error\Run->handleError(32, 'Module 'soap' a...', 'Unknown', 0)
#1 [internal function]: WHMCS\Utility\Error\Run->handleShutdown()
#2 {main}

We're getting the above error almost every time a user signs in (after they press the sign in button). If the page is refreshed it goes away.

Anyone experienced this? Is there a fix?

This is on version 7.9.1 on a supported PHP version (7.2.27-1+ubuntu18.04.1+deb.sury.org+1)

Thank you

using a clean version of Six or a custom template ??

We're using a custom template - but haven't removed anything from six - but I will revert to six and see if it occurs on it AFAICR it does.
