Hi Sharon, A couple of questions: has TILT already been working correctly on your server?-Or are you in the process of installing and testing for the first time?
This sure sounds like a web server configuration problem, your server appears to have been configured to only allow only the presentation of content, rather than presentation and receiving both. At least, that's what a 405 message typically indicates. Talk to your web administrator to find out. Cheers, -Chad
