Issue Cron fails with HTML code as output

Hi Everyone

I'm having an issue on a Wordpress website. The cron job fails when the plugins Yoast and WP-rocket are activated together.
Unfortunately the error output is not clear. I get the HTML code output, but cannot see any details.
Does anyone know where I have to look to see all of it?

Thanks for the help.

It seems that you have activated the wp-cron.php replacement option in WP Toolkit



In that case you'll find a "Scheduled Tasks" entry that you can edit. You could direct the output for that scheduled task to email, e.g.:



This will send you the full output by mail.

Thanks for the reply. Unfortunately I'm not able to send emails at all. No notifications, no cron job logs. I am using the external SMTP and it should be connected to Office365...

I've found a lot of articles, but non of them can get me in te right direction. I keep going in circles for hours now, why this isn't working...

Please open a support ticket so that an engineer can assist you. I suggest to first open a ticket on the email issue. If you cannot send mails, that will be best to solve first.

But You run a cron with curl ?
When run cron manually you get same error ?

What about php error_log when you run cron and get error.

Anyway in my case i found the problem with running the wp-cron.php through ssh:

/opt/plesk/php/8.3/bin/php /var/www/vhosts/<your-website.tld>/httpdocs/wp-cron.php

It throws the mentioned HTML and in the end:

PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 10485760 bytes) in /var/www/vhosts/.........

so had to edit in Plesk (Tools & Settings) the PHP.ini of the used php version. After that my problem solved.

It's a while ago, but I thought changing the cron URL from 'Run a PHP script' to the full URL www.abcd.com/wp-cron.php fixed the issue.
