Somethimes I faced with this error in my whmcs pages:

 

Oops!

Something went wrong and we couldn't process your request.

Please go back to the previous page and try again.

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

 

How can I fix this error?

I resolve this error with upgrade php version.
