Hi,

This one is driving me nuts!

I'm getting the following 404 message on page preview (of any page - even one with a basic 'hello world' doc type and template):

Server Error in '/' Application.

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /umbraco/preview/

Publishing the page works, and I can view it normally on the site. I have tried a republish and IIS reset.

Preview WAS working, and I have no idea from looking at the umbracoTraceLog what the issue could be, or what the trigger to break it was. The only lead I have is that I added a few extra styles into the RTE and did a few minor grid config changes before I noticed the break. That might be a red herring though. Does anyone have any pointers as to how to track this one down?

Cheers,

Sam
