Dashboard widget error 500, some errors for DB, security maintenance tab always on login

[Fritex]

Recent upgrade to 5.3.1, I have errors on Dashboard for "widget" - error 500.

- www/admin/dashboard.php?widget=Disabled

Plugin report shows some errors.

Wheneve I log into, I see the screen of security maintenance.

It's first time I got this.

Anayone?

From error.log file:

FastCGI sent in stderr: "PHP message: PHP Fatal error:  Uncaught Error: Class 'OA_Central_Dashboard' not found in /var/www/clients/client1/web7/web/lib/OA/Dashboard/Widgets/Disabled.php:33

Running latest Nginx, PHP 7.4, MariaDB 5.7.

Okay, I fixed this one.

I have to enable "updates", thereafter I have to enable "dashboard".

Dashboard working fine now for system administrator, but not working for the "user".

And still the "security maintenance" warning after log in.

 

 

Okay, after enabled "automatic updates" and set interval to "60", thereafter using Maintenance -> Menu to rebuild the menu cache.

Working for the "user" I have.

Okay, fixed "security maintenance" by manually adding to my Nginx vhost file as follows from below:

# 2022. OpenX security maintenance nesto
location ~ ^/(?!$|www/) {
    return 403;
}
location = /etc/database_action.xml {
    return 403;
}
location = /plugins/etc/openXDeliveryLog.xml {
    return 403;
}
location = /lib/RV.php {
    return 403;
}

And now I see in the Developer Console of my Web browser 403 HTTP error for them as it should be.

And now when I log out, log back, log out, log back, it's no more "security maintenance" screen, it goes directly to my "user" (no more system administrator) and works fine.
