Hi Gerry, Sorry for that issue but we pulled back those all plugins support and removed those plugins from the infinity one and other our WordPress themes. Also rev slider removed our themes for some reasons.
You can read them from this link: http://marketblog.envato.com/general/plugin-vulnerability/
We apologize for that but we won’t include those in our themes. You can do it same functionality with essential grid plugin. Please download infinity one WordPress theme your account section, included with new “Essential Grid” plugin and make your portfolios same with this plugin.
