My Xero private app has been working well for about 5 years using the provided php wrapper. After updating the cert today I now get 'ERROR: 1Curl error: ' when I call a put API.
The app was working fine yesterday but today the cert expired and I started receiving 'No certificates have been regestered for the consumer...'. I created a new cert and registered the .cer file on the Xero web site. I replaced my cert files (privatekey.pem & publickey.cer) on the web server. Now I can log (I get a token back from OAuth) in but I get the unhelpful Curl eror message.
Not sure where to go with this, it seems like a code issue, but the app worked fine yesterady.
