4.6 conflicts

Lame. Must have something to do with https://make.www.ads-software.com/core/2016/07/27/http-api-in-4-6/

I’ll try to take look at it; I’ve seen a couple other threads about it…

https://github.com/zaus/forms-3rdparty-integration/issues/69

Since you’re getting a different error than the other thread, what URL are you trying?

Actually, can you post the full debug dump? I’m having trouble reproducing any problems with 4.6

Ooh…someone else with the same problem https://core.trac.www.ads-software.com/ticket/37733

Found it, I used a malformed url after all… It did work with earlier versions of WP, but the new WP doesn’t allow // in an URL.

What’s your endpoint URL? The issue also affects querystring parameters, like if you were posting to https://someendpoint.com/submissions/?fid=1234&redirect=https://othersite.net — which should be URL-encoded anyway.
