Okay, I have a php script that has to be executed each 15 minutes, but that does not work. My other scripts just get executed just fine, and I can execute it via the command line.
# m h dom mon dow command
30 2 * * 1 /usr/bin/letsencrypt renew >> /var/log/le-renew.log
* 10 * * 0 php /var/www/html/slack/huiswerk_reminder/runner.php
* 17 * * 1 php /var/www/html/slack/huiswerk_reminder/runner.php
* 17 * * 2 php /var/www/html/slack/huiswerk_reminder/runner.php
* 14 * * 3 php /var/www/html/slack/huiswerk_reminder/runner.php
* 16 * * 4 php /var/www/html/slack/huiswerk_reminder/runner.php
*/15 * * * * php /var/www/html/slack/cijfercheck/cijfercheck.php
Only */15 * * * * php /var/www/html/slack/cijfercheck/cijfercheck.php wont get executed. What am I doing wrong??
Steps I have taken to try fix it:
Change */15 to 0,15,30,45

Why is my crontab not working, and how can I troubleshoot it?
It all does not work, and the weird thing is, the others work just fine, no problem at all…
So what am I doing wrong?

You need a blank line at the end of your crontab, or it won't work. Also try adding #!/bin/bash before your scripts to ensure they run in BASH, rather than some other shell.
If that doesn't work, then you can try offloading to a .sh script:
then you fill it out as a BASH script:
