 * Great plugin, very functional and comprehensive but in debug mode I’m getting
   the following Notice & Warning upon submission on a blank screen. The submission
   is recorded and everything seems to be functioning correctly.
 * > Notice: Use of undefined constant WPCF7_Submission – assumed ‘WPCF7_Submission’

   > php on line 594

   > 1210
 * Any suggestions?
 * Thanks in anticipation.

 * I corrected the notice, which should resolve both log entries. Please update 
   and confirm that you no longer get these issues. Also please consider donating
   to support this plugin’s development.
