Welcome to the Q&A Forum

And the rich snippets testing tool still shows that your authorship is verified for the pages that are showing in the SERPs? If so, run through this checklist, posted in GWT Help: http://support.google.com/webmasters/bin/answer.py?hl=en&answer=1306778 and see if there is anything you might have overlooked (like installing Authorship code twice, this is a pretty common issue.) If you still don't see any issues there, you might try running a few different queries for different type of content you have verified Authorship for. Google states that they only show Authorship information for the most relevant queries. What they deem as the most relevant queries can and does change. I've noticed that my Authorship information/photo will show for some keyword searches and not appear for others (alongside the same pages in search results). Searching for the URL almost always shows information.

And do a complete database backup before you start the process so you will have a method to revert if anything goes wrong! This process involves a lot of "moving parts" and themes can vary quite a bit etc, so it's critical to build an escape hatch before you start. Paul
