I get an error message when Moderating Profile Photos

Fatal error: Uncaught TypeError: PH7\Framework\Layout\Html\Design::htmlTag(): Return value must be of type string, none returned in /home/website/domains/website/public_html/sdc/_ikkanhet/framework/Layout/Html/Design.class.php:914 Stack trace: #0 /home/website/domains/website/public_html/sdc/_ikkanhet/app/system/core/classes/design/AvatarDesignCore.php(116): PH7\Framework\Layout\Html\Design->htmlTag() #1 /home/website/domains/website/public_html/sdc/_ikkanhet/app/system/core/classes/design/AvatarDesignCore.php(94): PH7\AvatarDesignCore->showAvatarOnGoogleLink() #2 /home/website/domains/website/public_html/sdc/_ikkanhet/data/cache/pH7tpl_compile/admin123_1c5620b25a575857051dc7875dc88b2c/base/moderator/avatar.cpl.php(15): PH7\AvatarDesignCore->lightbox() #3 /home/website/domains/website/public_html/sdc/_ikkanhet/framework/Layout/Tpl/Engine/PH7Tpl/PH7Tpl.class.php(353): require('...') #4 /home/website/domains/website/public_html/sdc/_ikkanhet/data/cache/pH7tpl_compile/public_main/base/layout.cpl.phplayout.cpl.php(15): PH7\Framework\Layout\Tpl\Engine\PH7Tpl\PH7Tpl->display() #5 /home/website/domains/website/public_html/sdc/_ikkanhet/framework/Layout/Tpl/Engine/PH7Tpl/PH7Tpl.class.php(353): require('...') #6 /home/website/domains/website/public_html/sdc/_ikkanhet/framework/Mvc/Controller/Controller.class.php(85): PH7\Framework\Layout\Tpl\Engine\PH7Tpl\PH7Tpl->display() #7 /home/website/domains/website/public_html/sdc/_ikkanhet/app/system/modules/admin123/controllers/ModeratorController.php(152): PH7\Framework\Mvc\Controller\Controller->output() #8 [internal function]: PH7\ModeratorController->avatar() #9 /home/website/domains/website/public_html/sdc/_ikkanhet/framework/Mvc/Router/FrontController.class.php(656): ReflectionMethod->invokeArgs() #10 /home/website/domains/website/public_html/sdc/_ikkanhet/framework/Mvc/Router/FrontController.class.php(615): PH7\Framework\Mvc\Router\FrontController->runController() #11 /home/website/domains/website/public_html/sdc/_ikkanhet/app/Bootstrap.php(92): PH7\Framework\Mvc\Router\FrontController->runRouter() #12 /home/website/domains/website/public_html/sdc/index.php(45): PH7\Bootstrap->run() #13 {main} thrown in /home/website/domains/website/public_html/sdc/_ikkanhet/framework/Layout/Html/Design.class.php on line 914

The PH7 folder doesn't exist, I think that's why

How should I get this right?
