There are problems with this modifications that I actually did bring under your attention via pm some time ago.
From webmaster:
Dear webmaster of
http://reptile-parrots.com/forums/,
When indexing the deep links to your app, we detected that the content of 2 app pages doesn’t match the content of the corresponding web page. This is a bad experience for your users because they won’t find what they were looking for on your app page. We won’t show deep links for these app pages in our smartphone search results. This is an important issue that needs your immediate attention.
Google systems have detected that your desktop site URLs redirect smartphone users to the homepage of the smartphone site rather than the page they found in Search results. This critical issue causes problems for Googlebot for smartphones because it can’t access your smartphone URLs. It also confuses your users.
After disabling this modification the problem was resolved.
