You site has meta robots tag set to noindex. This is the reason its not indexed. Login to Wordpress & Go to > Setting > Reading > Remove the check from "Search Engine Visibility" > Save Changes
Look for page source of your web pages and see if you are seeing this meta tag - 'noindex'. If you are finding it probably you are adding it to your website either through CMS (see Setting > Reading > Remove the check from "Search Engine Visibility"), and check the header.php files of your wordpress theme for the 'noindex' tag. If it is so remove it. 'noindex' tag is also specified sometimes in you robots.txt file kept the website root folder, find this tag and delete it. thanks.
Also Google Crawls changes in structure of website after the Design is changed and will Index new website before that it will De Index old website and index Web Pages/URL from Re-Designed website. Make sure to Update the Sitemap of the Wordpress Website using Plugin and update the Google About the same from WebMaster Tools... And build some quality backlinks to the website's inner pages which will help in faster indexing on Google.
