Without a link to your forum or an example of the plugin code, it’s going to be hard to help. The blank screen is almost certainly a 500 error, so it should be logged somewhere, depending on your server configuration.

If you disable the plugin and everything works, you know the problem is with the plugin. So, you need to fix that. Without posting the plugin, it will be hard for anyone to help you fix it.
