[Plugin: Now Reading Reloaded] Plugin interfers with login process

Hi,

Whenever I have No Reading Reloaded activated, I have trouble loging in WordPress using an external publish client. As soon as I disable it, I can log in fine, so I assume the plugin for reason is interfering with the login process. I have no idea how to resolve this issue without having to uninstall my favourite pluging! Any help would be appreciated.
