Hello!
Looks like one of the tables wasn’t created for some reason. to fix it please open the file core/PluginBase.php and temporary change this:
if($dbversion<$this->dbVersion)
for this
if(true)
This will force the plugin to create the tables again, after that please try again.
Once the plugin submit the form correctly you can revert this change if you want or it will automatically removed in the next plugin update.
Regards!
