Question

Im working on a ical feed for that displays my woocommerce bookings but can't seem to get it to work. Could anyone please check my code for errors?

Answer 1

Your editor is not ending a line with CRLF, but rather a simple LF.

Add this code <?php echo "\r\n" ?> to each buffer line in your script.

Do it like this:

BEGIN:VCALENDAR<?php echo "\r\n" ?>
VERSION:2.0<?php echo "\r\n" ?>
