can you point me to the current specs for this? We’ve been doing a php Curl (http method) for many years. I just upgraded my phplist last week and now this method is failing. Not sure if the URL construct has changed since. Thanks!
Check the change log of the version you updated to (and any intervening versions) to see if changes were made to remote form submission or validation. I think there were a few security improvements last year.
If you’re using curl then you may have been using HTTP POST which I mentioned, already.
