Click to Chat facilitates the users to delete the plugin settings while uninstalling/deleting the plugin. This is achieved by checking the option “Delete this plugin settings when uninstalls”.
Whenever we re-install the plugin, previously assigned values to the plugin will be deleted if we check this option. If this option is unchecked, whenever we uninstall the plugin and re-install it, the previous plugin values get restored automatically.
Navigate to Click to Chat –> other settings –>Debug, Troubleshoot.
