To fix and make it compatible with wpForo menu please navigate to Dashboard > Forums > Settings > Styles admin page, put this CSS code in Custom CSS Code textarea, save it, delete all caches, navigate to forum front-end and press Ctrl+F5 to reset browser cache:
#wpforo #wpforo-wrap.wpf-dark #wpforo-menu li.menu-item-has-children a{ padding-right:30px}
#wpforo #wpforo-wrap #wpforo-menu li { border-right: #bcbcbc 1px solid; position: relative;}
