From your main page of quotes, all links work ok:
https://artuccino.com/index.php/quotes/?aut=The%20Buddha

But from your sidebar, the path is not correct (see bold below):
https://artuccino.com/artuccino/quotes/?aut=The%20Buddha

Please, revise your settings to rename the name (slug) of page wich contains your main quotes.
Maybe –quotes– instead of –artuccino-…

Best regards.

sorry, the correct function for single events is:
wp_schedule_single_event( $time, 'your_event' );

may be scheduling single events and replacing start time with a defined variable.

In wp_schedule_event, replace time() with a defined variable:
$time = strtotime("september 30, 23 hours 59 minutes 59 seconds");
now $time is a fixed value to schedule your event.

define an array() with the twelve values and that’s all ??

Just replace time() with a defined variable:
$time = strtotime("today 0 hours 1 minutes 0 seconds");
now $time is a fixed value to schedule your event…
then 'hourly' repeats every hour at xxh 01m 00s.

Is really simple [gallery columns=x] where x is the number of columns to display.
