This morning I made WordPress Google Form v0.46-beta-3 available for download from this site. I have not posted this version to the WordPress plugin repository as it still needs some testing. This beta release includes new checking to try and detect when the form data wasn’t actually posted to Google and if detected, will suppress the confirmation page (if used) so the Google error will not be missed by the user.
Download the beta release and please let me know if you run into any issues.
