HTML Improvements & Other Data Disappeared - How Do I Get It Back?

[RTT_STILLEN]

Hello,I am missing data in my webmaster tools - specifically in the HTML improvements and the site links section.  The site is indexed by Google and is showing up in the SERPs. I've checked site site with www in the front of the URL and without.  However, no data is showing up in these.  In other sections data is showing up (crawl errors, search queries, etc).  Any help in getting access to the data would be very much appreciated. Thank you!

That's probably a GWT glitch and it should be fixed soon. You can report it in the Google Webmasters forums if you like.
