I use a plugin (Companion Auto Update) for auto-update plugins. This is using the core function of Wordpress where you can force auto-update for plugins.
All the plugins is updated when an update is available except UpdraftPlus WordPress Backup Plugin
This has been tested by me but also by the plugin author of (Companion Auto Update) see here.
I am on a VPS. I tried different server settings but seems this is not solving the issue.
I am asking why if i update manually all is done very fast (less than 2 minutes) and the auto-update of Wordpress seems to be unable to update automatically UpdraftPlus WordPress Backup. When Wordpress update his version i suppose is more bigger than 7 MB who is the size of UpdraftPlus WordPress Backup.
PHP error has to say:
wp-cron.php' (request: "POST /wordpress/wp-cron.php?doing_wp_cron=***7500") execution timed out (120.770567 sec), terminating
I tried some server settings changes but this doesn't help. Any idea why there is this issue and how can be solved? Can be a Wordpress auto-update process issue?
