 * me too with a new installation on my plesk server. I am using oxygen builder 
   to design the website, but failed to access to the site once WP Mail SMTP is 
   activated. very frustrating. It does not seem like a wordpress version issue 
   as I tried to downgrade WP to 5.4.2, and the issue still there. I suspect there
   might be some errors in other areas, e.g. coding errors etc.
    here is some information
   regarding the error:

 * Hi,
 * it looks like your WP site is not able to create the needed database tables.
 * Please follow the instructions in the [tutorial here](https://wpmailsmtp.com/docs/how-to-troubleshoot-action-scheduler-issues-wp-mail-smtp-2-1-1/).
 * If you’re still experiencing this issue, contact your hosting support to look
   into the MySQL database logs. It could be due to some database misconfiguration.
 * Take care!

 * [@capuderg](https://wordpress.org/support/users/capuderg/) I did follow the tutorial,
   but for some reason when I activate the Action Scheduler plugin it does not appear
   in the tools section.
 * Did you ever seen this issue?

 * Hi [@mshell](https://wordpress.org/support/users/mshell/),
 * maybe some other plugin is hiding that page… The menu item is hidden, but you
   can still access the Action Scheduler (AS) page, by going directly to `wp-admin/
   tools.php?page=action-scheduler`. So go to [http://yourdomaingoeshere.xyz/wp-admin/tools.php?page=action-scheduler](http://yourdomaingoeshere.xyz/wp-admin/tools.php?page=action-scheduler)
   and you should see the AS page.
 * Take care!

 * Hi [@capuderg](https://wordpress.org/support/users/capuderg/)
 * I found the solution in another post.
 * In my wpconfig the PHPMailer\PHPMailer\SMTP class was defined before the WP core
   can.
 * Issue is solved now and i’m able to use the plugin.
 * Thanks!
