It’s a permissions issue. Run this on SSH:

​

chmod -R 0755 /var/www//wp-content/plugins
chown -R www-data /var/www//wp-content/plugins

note: The first grants writing permissions, while the second ensures the user who needs the permission is correctly set

what do you think about this:

btw: have the following notes in the Dashboard:

​

The WP Job Manager Add-On requires WP All Import Pro or Free, and the WP Job Manager plugin.
Dismiss this notice. The plugin restricted-site-access/restricted_site_access.php has been deactivated due to an error: Plugin file does not exist. The plugin woocommerce/woocommerce.php has been deactivated due to an error: Plugin file does not exist. The plugin wp-job-manager/wp-job-man
