Problem solved:
When I upgraded to 3.6, I also checked the JetPack functionalities, and I activated “photon”.
When you activate “photon”, the get_the_post_thumbnail() wordpress function returns a link to “photon” instead of your own library and this seems to be a problem for the feature_content_slider plugin.
To solve it just deactivate Photon on your jetpack admin page, and it will work.
Same here!! 🙁

It seems that the class “img_right” is not formed properly: inside the <img src=”….”> instead of the thumbnail image, it’s putting the text with the image description.
Maybe it could be a problem with the database query where the plugin retrieves the image URL from the database?
any help will be wellcome 🙂
