I am seeing erratic issues with this plugin.... it is not connecting to the linked media items via various short codes that I have in posts or pages.
Sooooo.... what I am saying is it doesn't seem to be limited to any one type of media.
The message that appears where the short code is inserted is this...
" No media items found. "
Before you ask.... YES, I de-activated all of my plugins... I even reverted back to v1.0 of the plugin... and the issues persists.... this also occurs with your latest version 1.1.1
and yes.... my caching plugin was turned off... the caches of 3 browsers on the mac... Safari, Firefox, and Chrome ALL emptied and eventually showed the error.
Sometimes the short code connects and other times it doesn't.
