We've just launched a competition entry form page on a website. It's had thousands on entries and has been rigourously cross browser tested but we've had a few complaints that people simply cant access the page and they get a 404 error.
Unfortunately none of the complainants have been happy to give us browser and OS details but we have a feeling that it might be Vista and ie9 which are playing up.
We simply cant replicate any issues. Has anyone had any similar problems? If so, was there a solution?
