There should be 5 screens that slide in the main box. Now, only the first screen appears, and it doesn't change.
I installed W3 Total Cache, and after playing with the settings (recommended settings from W3 install site), and once I noticed the jquery slider was broken, I uninstalled the plugin. Then I went into the FTP and removed the files from wp-content/ (as suggested in another thread).
I still don't have a working slider.
I've asked my host to clear the cache from the server in hopes that will help.
