Had same problem: Post Expirator was creating the events to expire the posts, but the events wouldn’t execute when cron was firing. Did what unireverse suggested. Saw an error about not being able to spawn more http requests. Googled that. Turned out I was missing php5-curl on my installation. After I installed php5-curl and reloaded apache, the events started to get executed just fine.
Thank you SwansonPhotos. Mime types were missing on my server for silverlight to work. So uploader now works with silverlight in my host albeit with the same limitation as flash (no drag/drop). I guess it is what it is. Thank you again.
Probably, but…
A. I don’t think WP has dropped support for IE8 yet.
B. I see the same problems in IE9 that I see in IE8. Silverlight does not work and flash does not support drag-n-drop.
