WordPress Twenty Fourteen themes ‘Missing: Update’

How to fix WordPress Twenty Fourteen themes ‘Missing: Update’ error from Google’s Structured Data Testing Tool

This error is coming due to missing update date meta field. We need to update WordPress template to fix this issue. Adding updated value in time tag will fix this issue.

  1. Edit template-tags.php from wp-content/themes/twentyfourteen/inc
  2. Look <time class=”entry-date” datetime=”%2$s”>%3$s</time> in
  3. Look <time class=”entry-date updated” datetime=”%2$s”>%3$s</time> in twentyfourteen_posted_on()

This will fix the issue.

Spring MVC with thymeleaf

Spring MVC application with thymeleaf

Objective: Substitue view-layer web technologies such as JSP.

Pre-req: Spring STS as development environment

Why thymeleaf?: 

  • Natural templating for easy prototyping: display your templates statically in a browser (without running your app server).
  • Complete integration with Spring MVC (SpringStandard): form binding, property editors, internationalization, etc.
  • Full (and extensible) internationalization support: easy inclusion of externalized messages into templates.
  • URL rewriting capabilities for adding context and session information to URLs.
  • Spring Security support.
  • Out-of-the-box: templates can be read as classloader or ServletContext resources, as well as files (from the filesystem) and by calling URLs.


  1. Create spring mvc project
    • Go to File > New > Spring MVC Project
    • Select project name (ess) and top level package (com.njoshi.ess)
  2. Right click on project name > run on server to make sure project configuration is working
  3. Add thymeleaf dependancy
    • Open pom.xml
    • Add following dependancy
    • <dependency>
  4.  SpringTemplateEngine
    • Configure thymeleaf template engine in ess/src/main/webapp/WEB-INF/spring/appServlet/servlet-context.xml
  5. Changes in home.jsp
    • Change home.jsp to home.html
