isapan,
Thanks for your help and for pointing out to me where the older versions of the plugins are at (right sidebar, the blue box “FYI” has a link “Other Versions”). I downloaded the 2.1 version and replaced the Scripts folder within my version (located at wp-content/plugins/wp-featured-content-slider/scripts) with the version in 2.1. However, there is no change.
One thing to note is that the problem occurred after moving my website from one host location to a new one. It wasn’t a problem with updating the plugin itself. (I don’t know if that makes a difference.)
Any ideas? Or, should I simply delete the plugin entirely and load up a new version? And if so, which version would you recommend? (I’m on WP 3.2.1)
Thanks so much again.
