Beginning with version 15
cformsII does not have built-in Tracking Database support anymore. However it allows for arbitrary plugins to process the validated form submissions. This plugin implements the old tracking database submission feature via this mechanism, but it will not have any new features. E.g. there will not be any user interface.
You will have to rely on direct database access via any MySQL software to view the data or you can use the
Unofficial CForms II table display to view the tracking database on any page via Shortcodes.
There are two tables involved in the Tracking DB: "cformssubmissions" and "cformsdata", which are prefixed by the wordpress installation prefix that is "wp_" by default.
The minimum required cformsII version for this plugin is 15.0.
