Vernon Fowler on "[Plugin: WP Survey And Quiz Tool] PHP Session error"

After submitting a quiz the response screen shows a PHP session error.

I'm using version 2.13.1 of the plugin and version 3.7.1 of WordPress. This particular error is reproducible and only seems to have cropped up in the last month or two.

I'm considering switching to Wp-Pro-Quiz which seems to have the features we need.
