Hi kkathman,
Unfortunately we are not the codders of the WP Super Cache plugin and have only created this addon to empty the cache more easily through the menu.
Our plugin can’t ruin a site because it only adds an additional menu entry in the administration which executes the empty cache function of the main plugin: WP Super Cache. Your problems probably come from the main plugin: WP Super Cache.
If you need more help with this topic, I would recommend posting it to the support forum of the WP Super Cache plugin, where more people will be able to help you: wordpress.org/support/plugin/wp-super-cache.
Best regards.
