This is a weird issue which is very difficult to explain......
I have used this plugin for many months without a problem.
As of today we noticed a problem - its only on the blog home page - where posts are shown as excerpts.
We add videos to posts simply as httpv://youtu.be/zdgMo7BjA0Y
[we have noted that we no longer need to add the v]
For the top (most recent) post the video shows ok but afterwards it some how pulls in text from the next two posts
Use IFRAME embed code TICKED
Show embeds in post excerpts as NOTHING
As this is a live site I didn't want to leave this showing so had to enter full embed code to get video to display properly.
Any ideas what might be wrong ?
