My Highrise URL and API token check out but nothing gets into Highrise. When I set debug to true, I see this 37signals error message in the [body] of the [response] array:
Oops, that isn’t right.
You may have typed the URL incorrectly.
Check to make sure you’ve got the spelling, capitalization, etc. exactly right.
The URL and token look correct in the debug as well.
I'm using WordPress 3.5.1, Gravity Forms 1.6.12, Gravity Forms Highrise Plugin 2.5.1, and a theme based on Genesis Framework 1.9.1.
