Note: This problem should only affect those who downloaded version 2.2 yesterday, before 10:00 pm (when we slipped in the fix into the distribution along with a fix that will prevent blank pings from reaching your site).
If, when using bookmarklets, the "TrackBack entries to ping" pull-down (or single line in the case of pages with just one TB-enabled post) doesn't show up, you may be seeing the same problem that The One True b!X noticed.
Ben writes about the technical reasons for the problem:
"The problem was that LWP::UserAgent, after fetching the page from the original server (www.movabletype.org/trackback/) then tried to parse the
section using the HTML::HeadParser module. But that module isn't included with LWP::UserAgent, so it was dying. So I read up on it, and I found out the way to turn off the automatic parsing. And so now it's automatically turned off when fetching documents."As I said earlier, if you downloaded after around 10:00 pm yesterday, this problem is already fixed. If, however, you downloaded it after this time, you'll want to download a new copy of the distribution and replace two files:
lib/MT/App/CMS.pm
This will fix the bookmarklet problem
lib/MT/App/Trackback.pm
This will prevent you from receiving blank pings
