I'm not quite sure how to explain (technically), but our website was transfered over to a WordPress platform a couple years ago. However, the 'old' pages (which I am unable to locate in my WordPress) keep popping up on Google searches. They are the same URLs as the current pages, except they end in .php, and are the old versions with old info. They are not visible as pages in my dashboard. I've periodically used Google Webmaster Tools to remove the URLs from search results and cache, but they eventually reappear. I would love to find them and remove them internally, I just don't know how! I'm fairly new at handling WordPress webpages, so any guidance would be greatly appreciated!
Here is a link to the regular search results: https://www.google.com/search?q=urth+yoga&aq=f&oq=urth+yoga&aqs=chrome.0.59j5j61l2j0l2.1933&sourceid=chrome&ie=UTF-8
And the 'more results from website' search results (where you can see the links ending in .php - they are the old pages I want to remove / delete): https://www.google.com/search?q=urth+yoga&aq=f&oq=urth+yoga&aqs=chrome.0.57j5j61l2j0l2.1230&sourceid=chrome&ie=UTF-8#q=+site:urthyoga.com+urth+yoga&sa=X&ei=qqOGUabtFqTL0gH50oG4AQ&ved=0CFcQrAM&bav=on.2,or.r_cp.r_qf.&bvm=bv.45960087,d.dmQ&fp=61967fd3e70e14f3&biw=1274&bih=679
Thanks in advance!
