I think you should compare the php.ini file. What about uploading a phpinfo.php file in both webservers and compare them ?

put the bellow code inside a phpinfo.php file and open it in the browser. It will show the complete php setup.

<?php
phpinfo();
?>

you should contact your hosting provider since you have to change file permission to 644 . 644 gives you write permission which is needed for updating the file.

The best solution is to run a real cron-job on your server . You may contact your hosting provider in assisting to run a cronjob.

this plugin https://www.ads-software.com/plugins/wp-crontrol/ will give you insights on what’s going on with the wp-cron and why the posts are not published as scheduled.

looks like the wp_debug is turned on. Open wp-config.php file and search for

define( ‘WP_DEBUG’, true );

change true to false and the messages should disappear.

at wp-config.php set this

$theme_root = WP_CONTENT_DIR . ‘/var/www/wp-content/themes’;

it think it will do the job.

the website is up and running. do you still face this issue ?

You better look into php error logs or turn on wp_debug . You will find useful information here :

after trying the above, do you get any visible or logged error ?

you have to edit the nginx.conf , usually stored under /etc/nginx/nginx.conf . Edit or add

client_max_body_size 64M or as match as you wish. reload nginx and it should work.
