I have this plugin passing W3C Validation after a small change.
If you go into your WordPress SQL Database, and go to the WP_Options table, in there you will find st_widget. This contains the information for the 3 JavaScript files you will need for this plugin. I removed the ‘charset=”utf-8″ from the first and last scripts. I found the plugin ran successfully on my site, and the site now passes W3C validation.
