[Plugin: WordPress Varnish] Nothing happens when i click on the button

I have the same

You can take it from here https://github.com/pkhamre/wp-varnish …But plugin doesn’t work ??

I have tested this plugin with WP 3.1 and got it working with these settings:

• Get the latest version from github
  clone git://github.com/pkhamre/wp-varnish.git
• Add these lines to /etc/varnish/default.vcl:

After backend definition
acl purge {
  "localhost";
}

And inside sub vcl_recv
  if (req.request == "PURGE") {
    if(!client.ip ~ purge) {
      error 405 "Not allowed.";
    }

    purge("req.url ~ ^" req.url "$ && req.http.host == "req.http.host);
  }

• Activate plugin from WordPress admin panel

Ok, so this is incredibly dumb, and I’m reporting it as a bug.

The wp-varnish plugin, when installed from wordpress, is called “wordpress-varnish”. However, the plugin thinks it’s called ‘wp-varnish’.

This means, the javascript file with the addRow function the button triggers, 404s. And, even more joyfully, because you’re probably caching javascript to Timbuktu and back like I am, it will take you 4 hours after you fix it to actually get the file.

So, you need to remove the javascript file from your cache, and rename the plugin folder from wordpress-varnish to wp-varnish in your plugins folder.

did I mention this was dumb?
