I have a posted a new beta version of WordPress Google Form. This version (v.054-beta-6) fixes a problem reported today which happens when Logging is enabled on certain servers. This update will now test for the variables it wants to track before trying to use them.
This update also includes an enhancement with respect to HTTP API Transports. Previously the plugin allowed control of the various transport options in debug mode. Recently I found a case where it made sense to disable one of the transports on a permanent basis so I have pulled that functionality out of the debug module and moved it into the plugin core.Google Forms Beta (1436 downloads)
