Yes I meant disabling wp-cron.php and using other tools instead to run the cron jobs. I am running the following command from cron-job.org or Get Url Cron but neither of them updates the posts unless I press “Run Campaign” manually from within wordpress admin
I tried https://www.kux.de/extra/json/jci-step5.json and it is working fine as well. I switched to the default editor of wordpress but still it is generating the same exact error. I have no clue what is wrong
