MyBB has experienced an internal SQL error and cannot continue.

I cannot connect to both forum and admin panel.

What is the cause of this error?

I checked the config.php file and it's correct. I am using the latest version of MyBB.

Activate the logging of error in ACP » Home » Board Settings » Server and Optimization Options
You'll have more detals about the error

The same error exists in the admin panel. Therefore I cannot login to ACP.

inc/settings.php

$settings['errorloglocation'] = "./error.log";
$settings['errorlogmedium'] = "none";
$settings['errortypemedium'] = "both";

The settings are like this but the error.log file does not exist.

Change this:

$settings['errorlogmedium'] = "log";
