Right under the page header "Update Address Book Entry" (tpl_address_book_process_default.php) appears a line that says "Array()". I have no idea where it came from as I haven't even started editing that page. I searched for the string in Developer's Toolkit and in the document itself, but I can't find it anywhere.
The page works, I mean I can update the address and it saves it, but that line just came out of nowhere.
