Sorry to see that you had problem with my plugin, but like a said you have to do some test and backup before use this plugin, the plugin is not perfect and can have problem with other plugin and your configuration of wordpress(i tested in localhost and nicearma.com and it working fine, but i dont have a lots plugin install and the configuration is near to the configuration by default) if you want i can try to find the problem, you can put the list of plugin that you use in your site and i will try to find where is the problem
