I did a really quick check with the default theme, and although the ads did not display as I configured Easy Adsense for Librio, the page loaded completely, and with one ad displayed at the top (displayed in default way as it was before I configured Easy Adsense). I suppose that says that there could be an issue with Librio.
Did you test V2.51 with Librio on your test blog?
My argument is this: The only thing that changes from a working page to a non-working page is Easy Adsense. As soon as I change Easy Adsense back to the older version, my page works. To me, this most probably points to the newer version of Easy Adsense.
According to the error message in the page source, WP Super Cache complains about a missing closing html tag. I checked Librio’s footer.php, as well as a blog page that loaded, and the closing html tag is there. The error message may therefore be bogus.
Anything else I should check?
