Thanks. olgerfallaspainting.com is an example of one of the sites affected. I’ve disabled all plugins with the exception of MediaElement.js (which allows me to display video on the page – currently not working), Akismet, and Log Depreciated Notices (instead of wp_debug) and the theme has been changed to Twenty Eleven from it’s original.
There are no documented errors in the log file. At the bottom of the home page the code is displaying where the video should be. And on an internal article page (http://olgerfallaspainting.com/paint-removal-brick-chimney/) the code is bringing in a blank display with the link to download the video instead of running the file.
We’ve run all diagnostics on our servers and everything is fine. It just seems that regardless of the plugin we try to use there is a disconnect between the plugin requesting the file and the actual act of displaying and activating the file.
Again, this is happening across the board with every website I run since the 3.4.1 upgrade.
