The following issue has occured due to the location of the gantry/rockettheme CSS and JS files and locations blocked in the default joomla robots.txt file.Googlebot cannot access CSS and JS files
Google systems have recently detected an issue with your homepage that affects how well our algorithms render and index your content. Specifically, Googlebot cannot access your JavaScript and/or CSS files because of restrictions in your robots.txt file. These files help Google understand that your website works properly so blocking access to these assets can result in suboptimal rankings.
Files at these locations are the issue.
/components/com_roksprocket/assets/js/
/components/com_roksprocket/layouts/features/themes/showcase/
/components/com_roksprocket/layouts/features/assets/js/
/libraries/gantry/css/
/libraries/gantry/js/
/libraries/gantry/assets/jui/fonts/font-awesome4/
/modules/mod_rokajaxsearch/js/
/modules/mod_roknavmenu/themes/default/js/
/plugins/system/rokbox/assets/styles/
/plugins/system/rokbox/assets/js/
These files should be located in the /media/[your component] folder within joomla
a temporary work around is to add the following to the robots.txt file following the user-agent lineAllow: /components/com_roksprocket/assets/js/
Allow: /components/com_roksprocket/layouts/features/themes/showcase/
Allow: /components/com_roksprocket/layouts/features/assets/js/
Allow: /libraries/gantry/css/
Allow: /libraries/gantry/js/
