Hi,

We are having a problem with Umbraco Contour not submitting forms intermittently. Some website users are able to submit the form, but for others, they are getting one of two responses:

1. They are bounced to the top of the page, with no errors showing. They then click submit again, and then they get the thank you page, and the data shows in Contour;
2. They are bounced to the top of the page, with no errors showing. They then click submit again, and it jumps to the top of the page again, and never submits.

I've looked in the log in app_data/logs, but there is nothing of note in there. There is nothing in the umbracoLog table. There are entries appearing in contour, so for some people this is working.

I have tried using IE/FF and Chrome on a PC and Chrome on a Mac. Same result.

Has anyone seen this behavior? Have any ideas how we can track down what is going on?

Thanks,

Tony
