Widget Entries with Videos disaapeared from our site

I embed videos on our front page using widget entries, embedding the code from either YouTube or our Vimeo site.

This morning I discovered that two of our videos have disappeared along with the widgets that they used to be in. When I rebuilt the widgets and embedded the code like I always have in the past, the embed code shows up instead of the video (I left it up so people could see).

This is the second time in the past year that this has happened after an update and a maintenance update. I’m not sure what is happening. I’m not well versed in some of this stuff….
