I lied. Couldn’t go to sleep. Was curious about the report. Went to your Wedgewood demo site and saw the report. Switched to the same theme and made type smaller. Loaded the module.php to my Royals/Rebbes site. Same thing, goes to blank page. I’ve left it in that state if you want to see.
My A-D site, I restored to past state (older version) of module.php for now. At least I see what change you made (no sources). Are the labels (father, mother, date) there to facilitate CSV export?
