Dynamic Post Plugin Video Is Missing

If your video is missing from your tax article, then most likely, WordPress or a plugin stripped the iframe embed code because it did not recognize vimeo.com. 

Dynamic Post Plugin - An issue where the Tax Article video gets stripped out by WordPress Security Plugins.

Manual Fix: Log in as an Admin on the 3rd of the month, move the tax article to the trash, and then delete the article from the trash. Then go to the Dynamic Post control panel and "Post Article." When you are logged in as an Administrator, the video will not be stripped out.
