the server is not showing because of the line you commented.
because you changed the code for the server behavior, it is no longer recognized as the code footprint for the multiple record insert behavior.
change line 60:
//JED Removed per session start error on .com site if (!session_id()) session_start();
back to the original:
if (!session_id()) session_start();
the true cause of the error that you received that prompted you to comment that code is the comment at lines 1- 4:
<!--Originally mkr_Insert with Blank2Col template
added hidden update UserID and Dates from Cate3
added CSS formatting for categories
Prior step to MRT Server Behavior-->
this is going to cause the headers already sent error to occur due to html output to the page before the session_start() or headers() function.
