Opera 9.64. I also checked in Opera 10. There's no such error. Only "Error- unknown/bad credentials".

I don't know much about SQL injection. If that text you entered was something security related, then the server might have blocked your IP address. (Oh, this would not be the case since you were able to access your site in other browser.) Where exactly you typed that text, in Alias or Password? I didn't get any 406 error.

Thats a very nice thing. Good job. Yes, it would be better to get the info using other methods. @fabrydesign: The standard author, description meta tags can be used. Why have you gone to create new ones? I think, most of webmasters don't use author meta tags itself, and now bringing in new ones wouldn't be a wise choice. Instead you can help increase the usage of standard meta tags with your service. BTW keep it up, hope to see more features.
