This evening I uploaded v0.64-beta-3 of Google Forms. This version adds a check for the WordPress HTTP API cURL transport and issue a notification if it isn’t present.
There was a substantial change to the WordPress HTTP API between 3.6.1 and 3.7. I don’t know the full details of the change but what I found in pretty extensive testing is the streams and fsockopen transports work in 3.6.1 with the Google Forms plugin but from 3.7 and later, they do not.
However, the cURL transport does work and as long as it is available, the plugin will work as it always has. The problem is I cannot find any way to work with sites that don’t have the cURL transport available so I have added this check and issue a notice when it isn’t present.
Please download and test out this beta version and report any issues found.Google Forms Beta (642 downloads)
